Find the least common multiple and greatest common factor of 30 and 12to the nearest thousandth
If M is the least common multiple of 90, 196, and 300, which of the following is NOT a factor of M? 选项: A、600 B、 700 C、900 D、2,100 E、4,900 答案: A 经典答疑 发起提问 提问: 点此查看答疑 听完答疑区各位老师的解答后,还是不太明白。老师们的思路不太一样,按照把M拆分成...
Example: Find the Least Common Multiple of 90 and 36 Step one:find the prime factors of 36. Since 36 is an even number, divide 36 by 2, which equals 18. Since 18 is still even, divide by 2 again to get 9. 9 can be divided by 3 to get 3. Since 3 is prime, we are done....

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b). We need to calculate greatest common factor 3 and 9, than apply into the LCM equation.GCF(3,9) = 3 LCM(3,9) = ( 3 × 9) / 3 LCM(3,9) = 27 / 3 LCM(3,9) = 9...
Find the greatest common factor and the least common multiple of each pair of numbers below. 4, 5. 5, 7.相关知识点: 试题来源: 解析 (1) 1, 20. (2) 1, 35. (1) When two numbers are coprime, the greatest common factor is 1 and the least common multiple is their product. (2) ...
This gives us: 22x 5 x 7 = 2 x 2 x 5 x 7 = 140 The Least Common Multiple is 140. Example 2) Find the least common multiple of 144 and 78. As a product of prime factors: 144 = 2 x 2 x 2 x 2 x 3 x 3 = 24x 32 ...
(2) 1,21; 1, 7; 1, 22. (1) When one number is a multiple of the other, the greatest common factor is the smaller number and the least common multiple is the bigger one. (2) When two numbers are coprime, the greatest common factor is 1 and the least common multiple is their ...
