Given numbers are 672,806,416,257

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

The LCM of 672,806,416,257 is 69599712.

Find LCM of 672,806,416,257 with Prime Factorization

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

2 x 2 x 2 x 2 x 2 x 13 x 21 x 31 x 1 x 257 = 69599712

Therefore, the lowest common multiple of 672,806,416,257 is 69599712.

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.

672 x 806 x 416 x 257 = 57906960384

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.

672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672

806 : 1, 2, 13, 26, 31, 62, 403, 806

416 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 104, 208, 416

257 : 1, 257

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 672,806,416,257, is 1.

Now, the common factors can be found like this.

672:2x 2x 2x 2x 2x 3x 7

806:2x 13x 31

416:2x 2x 2x 2x 2x 13

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 2x 2x 2x 13 = 832

Therefore, the value for common factors is 832.

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 = 57906960384/(1x832)

LCM = 57906960384/832

LCM = 69599712

Thus, we can understand that the LCM of 672,806,416,257 is 69599712.
