Greatest common factor: 5 GCF(10, 15) = 5 2. Find the GCF of 42 and 56 using the prime factorization method. Solution: Prime factorization of 42: 42 =2× 3 ×7 Prime factorization of 56: 56 =2× 2 × 2 ×7 Common prime factors: 2, 7 ...
To factor a polynomial, first identify the greatest common factor of the terms. You can then use the distributive property to rewrite the polynomial in factored form. Recall that the distributive property of multiplication over addition states that a product of a number and a sum is the same ...
value common factor. You look at the list of common factors, like we have here, and determine which number is largest. In the case of 35 and 40, 1 and 5 are the only factors that they have in common, and 5 has a higher value than 1; therefore, 5 is the greatest common factor....
The greatest common factor (GCF) is often also called the greatest common divisor (GCD) or highest common factor (HCF). Keep in mind that these different terms all refer to the same thing: the largest integer which evenly divides two or more numbers.The greatest common factor of 8400, 3360...
The greatest common factor is exactly as it sounds: the greatest factors of two or more numbers. Example Find the common factors for 60 and 30 Begin by factoring both numbers. Find all factors that the numbers have in common. The product of all common factors is the greatest common factor...
- 若k = j + 1,则j和k是连续正整数。 - **结论**:任何两个连续正整数的GCD均为1(因为它们互质)。 - **充分性**:条件A足以唯一确定GCD(j, k) = 1,因此充分。2. **条件B**:jk能被5整除 - jk是5的倍数,但j和k的关系不唯一。 - **可能性分析**: - 若jk = 5,可能为(j=5,...
How To: Given a polynomial expression, factor out the greatest common factor. Identify the GCF of the coefficients. Identify the GCF of the variables. Combine to find the GCF of the expression. Determine what the GCF needs to be multiplied by to obtain each term in the expression. ...
