Given numbers are 647,202,892,646

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

The LCM of 647,202,892,646 is 18827516252.

Find LCM of 647,202,892,646 with Prime Factorization

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

2 x 647 x 101 x 446 x 323 = 18827516252

Therefore, the lowest common multiple of 647,202,892,646 is 18827516252.

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.

647 x 202 x 892 x 646 = 75310065008

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.

647 : 1, 647

202 : 1, 2, 101, 202

892 : 1, 2, 4, 223, 446, 892

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 647,202,892,646, is 1.

Now, the common factors can be found like this.

647:647

202:2x 101

892:2x 2x 223

646:2x 17x 19

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 75310065008/(1x4)

LCM = 75310065008/4

LCM = 18827516252

Thus, we can understand that the LCM of 647,202,892,646 is 18827516252.
