Given numbers are 647,374,184,398

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

The LCM of 647,374,184,398 is 4430133224.

Find LCM of 647,374,184,398 with Prime Factorization

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

2 x 647 x 187 x 92 x 199 = 4430133224

Therefore, the lowest common multiple of 647,374,184,398 is 4430133224.

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 374 x 184 x 398 = 17720532896

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

374 : 1, 2, 11, 17, 22, 34, 187, 374

184 : 1, 2, 4, 8, 23, 46, 92, 184

398 : 1, 2, 199, 398

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 647,374,184,398, is 1.

Now, the common factors can be found like this.

647:647

374:2x 11x 17

184:2x 2x 2x 23

398:2x 199

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 = 17720532896/(1x4)

LCM = 17720532896/4

LCM = 4430133224

Thus, we can understand that the LCM of 647,374,184,398 is 4430133224.
