So, we have, 56 = 2 × 2 × 2 × 7 and 84 = 2 × 2 × 3 × 7 . Now, HCF of 56 and 84 will the product of common prime factors with the lowest exponential power, that is, 7 and 2². So, HCF of 56 and 84 = 7 × 2 × 2 = 28. HCF of Two Numbers by Division ...
Whole Numbers All counting numbers along with zero form a set of whole numbers 0, 1, 2, 3, 4 --- whole numbers Any natural number is a whole number0 is a whole no. which is not a natural no. Integers Counting numbers + negative counting numbers + zero, all are integers -2, -1...
Prime numbers up to 100are all the prime numbers that come between 1 and 100. Any whole number which is greater than 1 and it is divisible only by 1 and the number itself, is known as a prime number. The formula of prime numbers helps in representing the general form of a prime numb...
Co-prime numbers are those with only one common element. A set of co-prime numbers should consist of at least two numbers. The highest common factor in such numbers is only one. The greatest number among all the common factors of two or more numbers is called the HCF (Highest Common Fac...
In other words, a rational number is any number that can be expressed as the quotient of two integers with the condition that the divisor is not zero. Examples of rational numbers include $-\frac{1}{7}, \,\frac{-5}{18}, \,\frac{11}{18}, \,\frac{-17}{9}$, etc. ...
LCM of two numbers is the smallest positive integer which is divisible by both the numbers. Learn to find LCM of two fractions with the help of examples at BYJU’S.
Step 1: Select first 2 or 3 terms to crack the rule of the sequence. This will help in finding the missing number. For instance: if a sequence has 5 terms, we can start with the first three terms and check the rule applied.
Ans: We have to find the HCF of $196$ and $38220$ by using Euclid’s division algorithm. According to Euclid’s division algorithm, the HCF of any two positive integers $a$ and $b$, where $a > b$ is found as : First find the values of $q$ and $r$, where $a=bq+r$, $0\...
Let’s have a look at theco prime numbers definitionin mathematical terms along with the representation. What are Co-Prime Numbers? Suppose x and y are two positive integers such that they are called co prime numbers if and only if they have 1 as their only common factor and thus HCF(x...
A Trickier Example: HCF and LCM of 120 and 252 Let's look at an example with even larger numbers now. If we wanted to find the lowest common multiple and highest common factor of 120 and 252, we would be here a long time if we tried to do it by writing out all of the facto...
