Given numbers are 656,806,408,974

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

The LCM of 656,806,408,974 is 6566108016.

Find LCM of 656,806,408,974 with Prime Factorization

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

2 x 2 x 2 x 82 x 403 x 51 x 487 = 6566108016

Therefore, the lowest common multiple of 656,806,408,974 is 6566108016.

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.

656 x 806 x 408 x 974 = 210115456512

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.

656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656

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

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

974 : 1, 2, 487, 974

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 656,806,408,974, is 2.

Now, the common factors can be found like this.

656:2x 2x 2x 2x 41

806:2x 13x 31

408:2x 2x 2x 3x 17

974:2x 487

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 2 = 16

Therefore, the value for common factors is 16.

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 = 210115456512/(2x16)

LCM = 210115456512/32

LCM = 6566108016

Thus, we can understand that the LCM of 656,806,408,974 is 6566108016.
