Given numbers are 647,379,236,920

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

The LCM of 647,379,236,920 is 13310161640.

Find LCM of 647,379,236,920 with Prime Factorization

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

2 x 2 x 647 x 379 x 59 x 230 = 13310161640

Therefore, the lowest common multiple of 647,379,236,920 is 13310161640.

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.

647 x 379 x 236 x 920 = 53240646560

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.

647 : 1, 647

379 : 1, 379

236 : 1, 2, 4, 59, 118, 236

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 647,379,236,920, is 1.

Now, the common factors can be found like this.

647:647

379:379

236:2x 2x 59

920:2x 2x 2x 5x 23

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 = 53240646560/(1x4)

LCM = 53240646560/4

LCM = 13310161640

Thus, we can understand that the LCM of 647,379,236,920 is 13310161640.
