Given numbers are 862,156,272,128,357

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

The LCM of 862,156,272,128,357 is 256034688.

Find LCM of 862,156,272,128,357 with Prime Factorization

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

2 x 2 x 2 x 2 x 3 x 17 x 431 x 13 x 1 x 8 x 7 = 256034688

Therefore, the lowest common multiple of 862,156,272,128,357 is 256034688.

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.

862 x 156 x 272 x 128 x 357 = 1671394443264

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.

862 : 1, 2, 431, 862

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

272 : 1, 2, 4, 8, 16, 17, 34, 68, 136, 272

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

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 862,156,272,128,357, is 1.

Now, the common factors can be found like this.

862:2x 431

156:2x 2x 3x 13

272:2x 2x 2x 2x 17

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

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 2x 2x 2x 2x 2x 2x 3x 17 = 6528

Therefore, the value for common factors is 6528.

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 = 1671394443264/(1x6528)

LCM = 1671394443264/6528

LCM = 256034688

Thus, we can understand that the LCM of 862,156,272,128,357 is 256034688.
