6 multiples of 7 are: 14, 21, 28, 35, 42, and 49
1, 2, 3, 6, 7, 14, 21, 42 1, 7, 49
Using the prime factors of 14 and 6, the LCM is 42 (2 x 3 x 7).
The LCM (least common multiple) of 6;9;and 42 is 126 (42*3) (9*14) (6*21) Edited by: Emilio Aranda_EL Paso, Tx (Emilioa)
The LCM is 42.
The Least Common Multiple (LCM) of 6, 7, and 21 is 42.
The LCM of 6, 14, and 21 is 42
Oh, what a happy little question! To find the Least Common Multiple (LCM) of 6, 14, 21, and 49, we look for the smallest number that is a multiple of all these numbers. First, we find the prime factors of each number: 6 = 2 x 3, 14 = 2 x 7, 21 = 3 x 7, and 49 = 7 x 7. Then, we take the highest power of each prime factor that appears in any of the numbers. Multiplying these together, we get the LCM, which is 2 x 3 x 7 x 7 = 294.
The LCM of the given three numbers is 42

The LCM is: 441The GCF is: 7
To find the Least Common Multiple (LCM) of two numbers, you can use the formula LCM(a, b) = (a * b) / GCD(a, b), where GCD is the Greatest Common Divisor. For 14 and 21, the GCD is 7, so the LCM is (14 * 21) / 7 = 42. For 14 and 6, the GCD is 2, so the LCM is (14 * 6) / 2 = 42. Therefore, the LCM of 14 and 21 is 42, and the LCM of 14 and 6 is also 42.
LCM(9, 6, 21, 14) = 126
It is: 42
294
The least common multiple of the numbers 7, 18 and 21 is 126.
