Given numbers are 813,790,478,622

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

The LCM of 813,790,478,622 is 47739286830.

Find LCM of 813,790,478,622 with Prime Factorization

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

2 x 813 x 395 x 239 x 311 = 47739286830

Therefore, the lowest common multiple of 813,790,478,622 is 47739286830.

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.

813 x 790 x 478 x 622 = 190957147320

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.

813 : 1, 3, 271, 813

790 : 1, 2, 5, 10, 79, 158, 395, 790

478 : 1, 2, 239, 478

622 : 1, 2, 311, 622

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 813,790,478,622, is 1.

Now, the common factors can be found like this.

813:3x 271

790:2x 5x 79

478:2x 239

622:2x 311

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 = 190957147320/(1x4)

LCM = 190957147320/4

LCM = 47739286830

Thus, we can understand that the LCM of 813,790,478,622 is 47739286830.
