Calculate the LCM of 643,415,886,696

Given numbers are 643,415,886,696

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

The LCM of 643,415,886,696 is 82275785160.

Find LCM of 643,415,886,696 with Prime Factorization


2 643, 415, 886, 696
643, 415, 443, 348

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

2 x 643 x 415 x 443 x 348 = 82275785160

Therefore, the lowest common multiple of 643,415,886,696 is 82275785160.

LCM Formula to Find Lowest Common Multiple of 643,415,886,696

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.

643 x 415 x 886 x 696 = 164551570320

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.

643 : 1, 643

415 : 1, 5, 83, 415

886 : 1, 2, 443, 886

696 : 1, 2, 3, 4, 6, 8, 12, 24, 29, 58, 87, 116, 174, 232, 348, 696

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,415,886,696, is 1.

Now, the common factors can be found like this.

643:643

415:5x 83

886:2x 443

696:2x 2x 2x 3x 29

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 = 164551570320/(1x2)

LCM = 164551570320/2

LCM = 82275785160

Thus, we can understand that the LCM of 643,415,886,696 is 82275785160.
