Given numbers are 632,842,421,305

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

The LCM of 632,842,421,305 is 81151960.

Find LCM of 632,842,421,305 with Prime Factorization

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

2 x 421 x 316 x 1 x 1 x 305 = 81151960

Therefore, the lowest common multiple of 632,842,421,305 is 81151960.

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.

632 x 842 x 421 x 305 = 68329950320

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.

632 : 1, 2, 4, 8, 79, 158, 316, 632

842 : 1, 2, 421, 842

421 : 1, 421

305 : 1, 5, 61, 305

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 632,842,421,305, is 1.

Now, the common factors can be found like this.

632:2x 2x 2x 79

842:2x 421

421:421

305:5x 61

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 421 = 842

Therefore, the value for common factors is 842.

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 = 68329950320/(1x842)

LCM = 68329950320/842

LCM = 81151960

Thus, we can understand that the LCM of 632,842,421,305 is 81151960.
