Given numbers are 842,487,478,432

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

The LCM of 842,487,478,432 is 21168627696.

Find LCM of 842,487,478,432 with Prime Factorization

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

2 x 421 x 487 x 239 x 216 = 21168627696

Therefore, the lowest common multiple of 842,487,478,432 is 21168627696.

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.

842 x 487 x 478 x 432 = 84674510784

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.

842 : 1, 2, 421, 842

487 : 1, 487

478 : 1, 2, 239, 478

432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 842,487,478,432, is 1.

Now, the common factors can be found like this.

842:2x 421

487:487

478:2x 239

432:2x 2x 2x 2x 3x 3x 3

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 = 84674510784/(1x4)

LCM = 84674510784/4

LCM = 21168627696

Thus, we can understand that the LCM of 842,487,478,432 is 21168627696.
