Calculate the LCM of 686,418,856,951

Given numbers are 686,418,856,951

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

The LCM of 686,418,856,951 is 58357232472.

Find LCM of 686,418,856,951 with Prime Factorization


2 686, 418, 856, 951
343, 209, 428, 951

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

2 x 343 x 209 x 428 x 951 = 58357232472

Therefore, the lowest common multiple of 686,418,856,951 is 58357232472.

LCM Formula to Find Lowest Common Multiple of 686,418,856,951

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.

686 x 418 x 856 x 951 = 233428929888

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.

686 : 1, 2, 7, 14, 49, 98, 343, 686

418 : 1, 2, 11, 19, 22, 38, 209, 418

856 : 1, 2, 4, 8, 107, 214, 428, 856

951 : 1, 3, 317, 951

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 686,418,856,951, is 1.

Now, the common factors can be found like this.

686:2x 7x 7x 7

418:2x 11x 19

856:2x 2x 2x 107

951:3x 317

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 = 233428929888/(1x4)

LCM = 233428929888/4

LCM = 58357232472

Thus, we can understand that the LCM of 686,418,856,951 is 58357232472.
