Given numbers are 638,663,706,127

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

The LCM of 638,663,706,127 is 18963244014.

Find LCM of 638,663,706,127 with Prime Factorization

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

2 x 319 x 663 x 353 x 127 = 18963244014

Therefore, the lowest common multiple of 638,663,706,127 is 18963244014.

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.

638 x 663 x 706 x 127 = 37926488028

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.

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

663 : 1, 3, 13, 17, 39, 51, 221, 663

706 : 1, 2, 353, 706

127 : 1, 127

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,663,706,127, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

663:3x 13x 17

706:2x 353

127:127

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 = 37926488028/(1x2)

LCM = 37926488028/2

LCM = 18963244014

Thus, we can understand that the LCM of 638,663,706,127 is 18963244014.
