Given numbers are 631,631,775,220

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

The LCM of 631,631,775,220 is 21517100.

Find LCM of 631,631,775,220 with Prime Factorization

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

5 x 631 x 1 x 1 x 155 x 44 = 21517100

Therefore, the lowest common multiple of 631,631,775,220 is 21517100.

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.

631 x 631 x 775 x 220 = 67886450500

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.

631 : 1, 631

631 : 1, 631

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

220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 631,631,775,220, is 1.

Now, the common factors can be found like this.

631:631

631:631

775:5x 5x 31

220:2x 2x 5x 11

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

5x 631 = 3155

Therefore, the value for common factors is 3155.

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 = 67886450500/(1x3155)

LCM = 67886450500/3155

LCM = 21517100

Thus, we can understand that the LCM of 631,631,775,220 is 21517100.
