Calculate the LCM of 517,491,394,938

Given numbers are 517,491,394,938

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

The LCM of 517,491,394,938 is 46907371742.

Find LCM of 517,491,394,938 with Prime Factorization


2 517, 491, 394, 938
517, 491, 197, 469

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

2 x 517 x 491 x 197 x 469 = 46907371742

Therefore, the lowest common multiple of 517,491,394,938 is 46907371742.

LCM Formula to Find Lowest Common Multiple of 517,491,394,938

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.

517 x 491 x 394 x 938 = 93814743484

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.

517 : 1, 11, 47, 517

491 : 1, 491

394 : 1, 2, 197, 394

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 517,491,394,938, is 1.

Now, the common factors can be found like this.

517:11x 47

491:491

394:2x 197

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.

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 = 93814743484/(1x2)

LCM = 93814743484/2

LCM = 46907371742

Thus, we can understand that the LCM of 517,491,394,938 is 46907371742.
