Given numbers are 731,624,766,790,430

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

The LCM of 731,624,766,790,430 is 69007745040.

Find LCM of 731,624,766,790,430 with Prime Factorization

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

2 x 5 x 43 x 17 x 312 x 383 x 79 x 1 = 69007745040

Therefore, the lowest common multiple of 731,624,766,790,430 is 69007745040.

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.

731 x 624 x 766 x 790 x 430 = 118693321468800

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.

731 : 1, 17, 43, 731

624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624

766 : 1, 2, 383, 766

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

430 : 1, 2, 5, 10, 43, 86, 215, 430

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,624,766,790,430, is 1.

Now, the common factors can be found like this.

731:17x 43

624:2x 2x 2x 2x 3x 13

766:2x 383

790:2x 5x 79

430:2x 5x 43

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 5x 43 = 1720

Therefore, the value for common factors is 1720.

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 = 118693321468800/(1x1720)

LCM = 118693321468800/1720

LCM = 69007745040

Thus, we can understand that the LCM of 731,624,766,790,430 is 69007745040.
