Given numbers are 121,832,748,160,638

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

The LCM of 121,832,748,160,638 is 248156480.

Find LCM of 121,832,748,160,638 with Prime Factorization

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

2 x 2 x 2 x 2 x 2 x 11 x 11 x 26 x 17 x 5 x 29 = 248156480

Therefore, the lowest common multiple of 121,832,748,160,638 is 248156480.

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.

121 x 832 x 748 x 160 x 638 = 7686895124480

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.

121 : 1, 11, 121

832 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 64, 104, 208, 416, 832

748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748

160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160

638 : 1, 2, 11, 22, 29, 58, 319, 638

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,832,748,160,638, is 1.

Now, the common factors can be found like this.

121:11x 11

832:2x 2x 2x 2x 2x 2x 13

748:2x 2x 11x 17

160:2x 2x 2x 2x 2x 5

638:2x 11x 29

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

2x 2x 2x 2x 2x 2x 2x 2x 11x 11 = 30976

Therefore, the value for common factors is 30976.

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 = 7686895124480/(1x30976)

LCM = 7686895124480/30976

LCM = 248156480

Thus, we can understand that the LCM of 121,832,748,160,638 is 248156480.
