Given numbers are 756,478,470

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 756,478,470 is 42460740.

Find LCM of 756,478,470 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 378 x 239 x 235 = 42460740

Therefore, the lowest common multiple of 756,478,470 is 42460740.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

756 x 478 x 470 = 169842960

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756

478 : 1, 2, 239, 478

470 : 1, 2, 5, 10, 47, 94, 235, 470

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 756,478,470, is 2.

Now, the common factors can be found like this.

756:2x 2x 3x 3x 3x 7

478:2x 239

470:2x 5x 47

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2 = 2

Therefore, the value for common factors is 2.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 169842960/(2x2)

LCM = 169842960/4

LCM = 42460740

Thus, we can understand that the LCM of 756,478,470 is 42460740.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 163, 909, 545
