Given numbers are 631,340,989,129

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

The LCM of 631,340,989,129 is 636540180.

Find LCM of 631,340,989,129 with Prime Factorization

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

43 x 631 x 340 x 23 x 3 = 636540180

Therefore, the lowest common multiple of 631,340,989,129 is 636540180.

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 340 x 989 x 129 = 27371227740

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

340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340

989 : 1, 23, 43, 989

129 : 1, 3, 43, 129

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 631,340,989,129, is 1.

Now, the common factors can be found like this.

631:631

340:2x 2x 5x 17

989:23x 43

129:3x 43

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

43 = 43

Therefore, the value for common factors is 43.

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 = 27371227740/(1x43)

LCM = 27371227740/43

LCM = 636540180

Thus, we can understand that the LCM of 631,340,989,129 is 636540180.
