Calculate the LCM of 646,779,404,152

Given numbers are 646,779,404,152

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

The LCM of 646,779,404,152 is 10700344.

Find LCM of 646,779,404,152 with Prime Factorization


2 646, 779, 404, 152
2 323, 779, 202, 76
19 323, 779, 101, 38
17, 41, 101, 2

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

2 x 2 x 19 x 17 x 41 x 101 x 2 = 10700344

Therefore, the lowest common multiple of 646,779,404,152 is 10700344.

LCM Formula to Find Lowest Common Multiple of 646,779,404,152

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.

646 x 779 x 404 x 152 = 30902593472

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.

646 : 1, 2, 17, 19, 34, 38, 323, 646

779 : 1, 19, 41, 779

404 : 1, 2, 4, 101, 202, 404

152 : 1, 2, 4, 8, 19, 38, 76, 152

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,779,404,152, is 1.

Now, the common factors can be found like this.

646:2x 17x 19

779:19x 41

404:2x 2x 101

152:2x 2x 2x 19

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 19x 19 = 2888

Therefore, the value for common factors is 2888.

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 = 30902593472/(1x2888)

LCM = 30902593472/2888

LCM = 10700344

Thus, we can understand that the LCM of 646,779,404,152 is 10700344.
