Given numbers are 638,977,195,428

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

The LCM of 638,977,195,428 is 26011393980.

Find LCM of 638,977,195,428 with Prime Factorization

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

2 x 319 x 977 x 195 x 214 = 26011393980

Therefore, the lowest common multiple of 638,977,195,428 is 26011393980.

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 977 x 195 x 428 = 52022787960

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

977 : 1, 977

195 : 1, 3, 5, 13, 15, 39, 65, 195

428 : 1, 2, 4, 107, 214, 428

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,977,195,428, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

977:977

195:3x 5x 13

428:2x 2x 107

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 = 52022787960/(1x2)

LCM = 52022787960/2

LCM = 26011393980

Thus, we can understand that the LCM of 638,977,195,428 is 26011393980.
