Given numbers are 517,407,631,987

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

The LCM of 517,407,631,987 is 253478379.

Find LCM of 517,407,631,987 with Prime Factorization

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

11 x 47 x 1 x 37 x 631 x 21 = 253478379

Therefore, the lowest common multiple of 517,407,631,987 is 253478379.

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.

517 x 407 x 631 x 987 = 131048321943

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.

517 : 1, 11, 47, 517

407 : 1, 11, 37, 407

631 : 1, 631

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 517,407,631,987, is 1.

Now, the common factors can be found like this.

517:11x 47

407:11x 37

631:631

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.

11x 47 = 517

Therefore, the value for common factors is 517.

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 = 131048321943/(1x517)

LCM = 131048321943/517

LCM = 253478379

Thus, we can understand that the LCM of 517,407,631,987 is 253478379.
