Calculate the LCM of 649,338,436,938

Given numbers are 649,338,436,938

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

The LCM of 649,338,436,938 is 22428009604.

Find LCM of 649,338,436,938 with Prime Factorization


2 649, 338, 436, 938
649, 169, 218, 469

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

2 x 649 x 169 x 218 x 469 = 22428009604

Therefore, the lowest common multiple of 649,338,436,938 is 22428009604.

LCM Formula to Find Lowest Common Multiple of 649,338,436,938

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.

649 x 338 x 436 x 938 = 89712038416

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.

649 : 1, 11, 59, 649

338 : 1, 2, 13, 26, 169, 338

436 : 1, 2, 4, 109, 218, 436

938 : 1, 2, 7, 14, 67, 134, 469, 938

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 649,338,436,938, is 1.

Now, the common factors can be found like this.

649:11x 59

338:2x 13x 13

436:2x 2x 109

938:2x 7x 67

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 89712038416/(1x4)

LCM = 89712038416/4

LCM = 22428009604

Thus, we can understand that the LCM of 649,338,436,938 is 22428009604.
