Given numbers are 128,638,753,357

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

The LCM of 128,638,753,357 is 3658833024.

Find LCM of 128,638,753,357 with Prime Factorization

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

2 x 3 x 64 x 319 x 251 x 119 = 3658833024

Therefore, the lowest common multiple of 128,638,753,357 is 3658833024.

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.

128 x 638 x 753 x 357 = 21952998144

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.

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

638 : 1, 2, 11, 22, 29, 58, 319, 638

753 : 1, 3, 251, 753

357 : 1, 3, 7, 17, 21, 51, 119, 357

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,638,753,357, is 1.

Now, the common factors can be found like this.

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

638:2x 11x 29

753:3x 251

357:3x 7x 17

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 21952998144/(1x6)

LCM = 21952998144/6

LCM = 3658833024

Thus, we can understand that the LCM of 128,638,753,357 is 3658833024.
