Given numbers are 631,215,220,987

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

The LCM of 631,215,220,987 is 5891659620.

Find LCM of 631,215,220,987 with Prime Factorization

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

5 x 631 x 43 x 44 x 987 = 5891659620

Therefore, the lowest common multiple of 631,215,220,987 is 5891659620.

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 215 x 220 x 987 = 29458298100

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

215 : 1, 5, 43, 215

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

987 : 1, 3, 7, 21, 47, 141, 329, 987

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 631,215,220,987, is 1.

Now, the common factors can be found like this.

631:631

215:5x 43

220:2x 2x 5x 11

987:3x 7x 47

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

5 = 5

Therefore, the value for common factors is 5.

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 = 29458298100/(1x5)

LCM = 29458298100/5

LCM = 5891659620

Thus, we can understand that the LCM of 631,215,220,987 is 5891659620.
