Given numbers are 634,432,715,91

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

The LCM of 634,432,715,91 is 685404720.

Find LCM of 634,432,715,91 with Prime Factorization

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

2 x 13 x 317 x 216 x 55 x 7 = 685404720

Therefore, the lowest common multiple of 634,432,715,91 is 685404720.

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.

634 x 432 x 715 x 91 = 17820522720

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.

634 : 1, 2, 317, 634

432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432

715 : 1, 5, 11, 13, 55, 65, 143, 715

91 : 1, 7, 13, 91

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 634,432,715,91, is 1.

Now, the common factors can be found like this.

634:2x 317

432:2x 2x 2x 2x 3x 3x 3

715:5x 11x 13

91:7x 13

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

2x 13 = 26

Therefore, the value for common factors is 26.

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 = 17820522720/(1x26)

LCM = 17820522720/26

LCM = 685404720

Thus, we can understand that the LCM of 634,432,715,91 is 685404720.
