Given numbers are 251,646,637,129,280

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

The LCM of 251,646,637,129,280 is 266480465160.

Find LCM of 251,646,637,129,280 with Prime Factorization

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

2 x 7 x 251 x 323 x 91 x 129 x 20 = 266480465160

Therefore, the lowest common multiple of 251,646,637,129,280 is 266480465160.

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.

251 x 646 x 637 x 129 x 280 = 3730726512240

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.

251 : 1, 251

646 : 1, 2, 17, 19, 34, 38, 323, 646

637 : 1, 7, 13, 49, 91, 637

129 : 1, 3, 43, 129

280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 251,646,637,129,280, is 1.

Now, the common factors can be found like this.

251:251

646:2x 17x 19

637:7x 7x 13

129:3x 43

280:2x 2x 2x 5x 7

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

2x 7 = 14

Therefore, the value for common factors is 14.

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 = 3730726512240/(1x14)

LCM = 3730726512240/14

LCM = 266480465160

Thus, we can understand that the LCM of 251,646,637,129,280 is 266480465160.
