Given numbers are 731,270,436,128

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

The LCM of 731,270,436,128 is 1376853120.

Find LCM of 731,270,436,128 with Prime Factorization

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

2 x 2 x 731 x 135 x 109 x 32 = 1376853120

Therefore, the lowest common multiple of 731,270,436,128 is 1376853120.

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 270 x 436 x 128 = 11014824960

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

270 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 90, 135, 270

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

128 : 1, 2, 4, 8, 16, 32, 64, 128

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,270,436,128, is 1.

Now, the common factors can be found like this.

731:17x 43

270:2x 3x 3x 3x 5

436:2x 2x 109

128:2x 2x 2x 2x 2x 2x 2

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 2 = 8

Therefore, the value for common factors is 8.

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 = 11014824960/(1x8)

LCM = 11014824960/8

LCM = 1376853120

Thus, we can understand that the LCM of 731,270,436,128 is 1376853120.
