Given numbers are 128,685,254,956

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

The LCM of 128,685,254,956 is 2661351040.

Find LCM of 128,685,254,956 with Prime Factorization

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

2 x 2 x 32 x 685 x 127 x 239 = 2661351040

Therefore, the lowest common multiple of 128,685,254,956 is 2661351040.

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 685 x 254 x 956 = 21290808320

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

685 : 1, 5, 137, 685

254 : 1, 2, 127, 254

956 : 1, 2, 4, 239, 478, 956

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,685,254,956, is 1.

Now, the common factors can be found like this.

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

685:5x 137

254:2x 127

956:2x 2x 239

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 = 21290808320/(1x8)

LCM = 21290808320/8

LCM = 2661351040

Thus, we can understand that the LCM of 128,685,254,956 is 2661351040.
