Calculate the LCM of 638,911,417,308

Given numbers are 638,911,417,308

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

The LCM of 638,911,417,308 is 3393150684.

Find LCM of 638,911,417,308 with Prime Factorization


2 638, 911, 417, 308
11 319, 911, 417, 154
29, 911, 417, 14

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

2 x 11 x 29 x 911 x 417 x 14 = 3393150684

Therefore, the lowest common multiple of 638,911,417,308 is 3393150684.

LCM Formula to Find Lowest Common Multiple of 638,911,417,308

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 911 x 417 x 308 = 74649315048

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

911 : 1, 911

417 : 1, 3, 139, 417

308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,911,417,308, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

911:911

417:3x 139

308:2x 2x 7x 11

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

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 74649315048/(1x22)

LCM = 74649315048/22

LCM = 3393150684

Thus, we can understand that the LCM of 638,911,417,308 is 3393150684.
