Calculate the LCM of 638,199,880,231,428

Given numbers are 638,199,880,231,428

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

The LCM of 638,199,880,231,428 is 11411344560.

Find LCM of 638,199,880,231,428 with Prime Factorization


2 638, 199, 880, 231, 428
2 319, 199, 440, 231, 214
11 319, 199, 220, 231, 107
29, 199, 20, 21, 107

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

2 x 2 x 11 x 29 x 199 x 20 x 21 x 107 = 11411344560

Therefore, the lowest common multiple of 638,199,880,231,428 is 11411344560.

LCM Formula to Find Lowest Common Multiple of 638,199,880,231,428

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 199 x 880 x 231 x 428 = 11046181534080

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

199 : 1, 199

880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880

231 : 1, 3, 7, 11, 21, 33, 77, 231

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 638,199,880,231,428, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

199:199

880:2x 2x 2x 2x 5x 11

231:3x 7x 11

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.

2x 2x 2x 11x 11 = 968

Therefore, the value for common factors is 968.

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 = 11046181534080/(1x968)

LCM = 11046181534080/968

LCM = 11411344560

Thus, we can understand that the LCM of 638,199,880,231,428 is 11411344560.
