Given numbers are 128,253,306,920

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

The LCM of 128,253,306,920 is 24773760.

Find LCM of 128,253,306,920 with Prime Factorization

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

2 x 2 x 2 x 23 x 16 x 11 x 153 x 5 = 24773760

Therefore, the lowest common multiple of 128,253,306,920 is 24773760.

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 253 x 306 x 920 = 9116743680

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

253 : 1, 11, 23, 253

306 : 1, 2, 3, 6, 9, 17, 18, 34, 51, 102, 153, 306

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,253,306,920, is 1.

Now, the common factors can be found like this.

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

253:11x 23

306:2x 3x 3x 17

920:2x 2x 2x 5x 23

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 2x 23 = 368

Therefore, the value for common factors is 368.

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 = 9116743680/(1x368)

LCM = 9116743680/368

LCM = 24773760

Thus, we can understand that the LCM of 128,253,306,920 is 24773760.
