Calculate the LCM of 731,852,436,342

Given numbers are 731,852,436,342

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

The LCM of 731,852,436,342 is 3869530956.

Find LCM of 731,852,436,342 with Prime Factorization


2 731, 852, 436, 342
2 731, 426, 218, 171
3 731, 213, 109, 171
731, 71, 109, 57

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

2 x 2 x 3 x 731 x 71 x 109 x 57 = 3869530956

Therefore, the lowest common multiple of 731,852,436,342 is 3869530956.

LCM Formula to Find Lowest Common Multiple of 731,852,436,342

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 852 x 436 x 342 = 92868742944

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

852 : 1, 2, 3, 4, 6, 12, 71, 142, 213, 284, 426, 852

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

342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,852,436,342, is 1.

Now, the common factors can be found like this.

731:17x 43

852:2x 2x 3x 71

436:2x 2x 109

342:2x 3x 3x 19

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 3 = 24

Therefore, the value for common factors is 24.

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 = 92868742944/(1x24)

LCM = 92868742944/24

LCM = 3869530956

Thus, we can understand that the LCM of 731,852,436,342 is 3869530956.
