Given numbers are 731,540,986,780,429

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

The LCM of 731,540,986,780,429 is 1636986780.

Find LCM of 731,540,986,780,429 with Prime Factorization

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

2 x 2 x 3 x 5 x 13 x 17 x 43 x 9 x 29 x 1 x 11 = 1636986780

Therefore, the lowest common multiple of 731,540,986,780,429 is 1636986780.

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 540 x 986 x 780 x 429 = 130238668216800

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

540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540

986 : 1, 2, 17, 29, 34, 58, 493, 986

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

429 : 1, 3, 11, 13, 33, 39, 143, 429

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,540,986,780,429, is 1.

Now, the common factors can be found like this.

731:17x 43

540:2x 2x 3x 3x 3x 5

986:2x 17x 29

780:2x 2x 3x 5x 13

429:3x 11x 13

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 3x 3x 5x 13x 17 = 79560

Therefore, the value for common factors is 79560.

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 = 130238668216800/(1x79560)

LCM = 130238668216800/79560

LCM = 1636986780

Thus, we can understand that the LCM of 731,540,986,780,429 is 1636986780.
