Calculate the LCM of 731,132,869,731

Given numbers are 731,132,869,731

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

The LCM of 731,132,869,731 is 7622868.

Find LCM of 731,132,869,731 with Prime Factorization


11 731, 132, 869, 731
17 731, 12, 79, 731
43 43, 12, 79, 43
1, 12, 79, 1

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

11 x 17 x 43 x 1 x 12 x 79 x 1 = 7622868

Therefore, the lowest common multiple of 731,132,869,731 is 7622868.

LCM Formula to Find Lowest Common Multiple of 731,132,869,731

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 132 x 869 x 731 = 61295481588

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

132 : 1, 2, 3, 4, 6, 11, 12, 22, 33, 44, 66, 132

869 : 1, 11, 79, 869

731 : 1, 17, 43, 731

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,132,869,731, is 1.

Now, the common factors can be found like this.

731:17x 43

132:2x 2x 3x 11

869:11x 79

731:17x 43

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

11x 17x 43 = 8041

Therefore, the value for common factors is 8041.

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 = 61295481588/(1x8041)

LCM = 61295481588/8041

LCM = 7622868

Thus, we can understand that the LCM of 731,132,869,731 is 7622868.
