Given numbers are 178,470,746,421

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

The LCM of 178,470,746,421 is 6568690390.

Find LCM of 178,470,746,421 with Prime Factorization

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

2 x 89 x 235 x 373 x 421 = 6568690390

Therefore, the lowest common multiple of 178,470,746,421 is 6568690390.

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.

178 x 470 x 746 x 421 = 26274761560

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.

178 : 1, 2, 89, 178

470 : 1, 2, 5, 10, 47, 94, 235, 470

746 : 1, 2, 373, 746

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 178,470,746,421, is 1.

Now, the common factors can be found like this.

178:2x 89

470:2x 5x 47

746:2x 373

421:421

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 = 26274761560/(1x4)

LCM = 26274761560/4

LCM = 6568690390

Thus, we can understand that the LCM of 178,470,746,421 is 6568690390.
