Given numbers are 642,977,625,575,775

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

The LCM of 642,977,625,575,775 is 279511151250.

Find LCM of 642,977,625,575,775 with Prime Factorization

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

5 x 5 x 642 x 977 x 25 x 23 x 31 = 279511151250

Therefore, the lowest common multiple of 642,977,625,575,775 is 279511151250.

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.

642 x 977 x 625 x 575 x 775 = 174694469531250

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.

642 : 1, 2, 3, 6, 107, 214, 321, 642

977 : 1, 977

625 : 1, 5, 25, 125, 625

575 : 1, 5, 23, 25, 115, 575

775 : 1, 5, 25, 31, 155, 775

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,977,625,575,775, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

977:977

625:5x 5x 5x 5

575:5x 5x 23

775:5x 5x 31

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

5x 5x 5x 5 = 625

Therefore, the value for common factors is 625.

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 = 174694469531250/(1x625)

LCM = 174694469531250/625

LCM = 279511151250

Thus, we can understand that the LCM of 642,977,625,575,775 is 279511151250.
