Find LCM of 156,578,408,731,257 with Prime Factorization


2 156, 578, 408, 731, 257
2 78, 289, 204, 731, 257
3 39, 289, 102, 731, 257
17 13, 289, 34, 731, 257
13, 17, 2, 43, 257

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

2 x 2 x 3 x 17 x 13 x 17 x 2 x 43 x 257 = 996446568

LCM Formula to Find Lowest Common Multiple of 156,578,408,731,257

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.

156 x 578 x 408 x 731 x 257 = 6911353395648

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.

156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156

578 : 1, 2, 17, 34, 289, 578

408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408

731 : 1, 17, 43, 731

257 : 1, 257

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 156,578,408,731,257, is 1.

Now, the common factors can be found like this.

156:2x 2x 3x 13

578:2x 17x 17

408:2x 2x 2x 3x 17

731:17x 43

257:257

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 3x 17x 17 = 6936

Therefore, the value for common factors is 6936.

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 = 6911353395648/(1x6936)

LCM = 6911353395648/6936

LCM = 996446568

Thus, we can understand that the LCM of 156,578,408,731,257 is 996446568.
