Given numbers are 856,478,872,470

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

The LCM of 856,478,872,470 is 5240419160.

Find LCM of 856,478,872,470 with Prime Factorization

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

2 x 2 x 2 x 107 x 239 x 109 x 235 = 5240419160

Therefore, the lowest common multiple of 856,478,872,470 is 5240419160.

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.

856 x 478 x 872 x 470 = 167693413120

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.

856 : 1, 2, 4, 8, 107, 214, 428, 856

478 : 1, 2, 239, 478

872 : 1, 2, 4, 8, 109, 218, 436, 872

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

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 856,478,872,470, is 2.

Now, the common factors can be found like this.

856:2x 2x 2x 107

478:2x 239

872:2x 2x 2x 109

470:2x 5x 47

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

2x 2x 2x 2 = 16

Therefore, the value for common factors is 16.

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 = 167693413120/(2x16)

LCM = 167693413120/32

LCM = 5240419160

Thus, we can understand that the LCM of 856,478,872,470 is 5240419160.
