Given numbers are 642,627,631,323

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

The LCM of 642,627,631,323 is 1439327406.

Find LCM of 642,627,631,323 with Prime Factorization

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

3 x 19 x 214 x 11 x 631 x 17 = 1439327406

Therefore, the lowest common multiple of 642,627,631,323 is 1439327406.

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 627 x 631 x 323 = 82041662142

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

627 : 1, 3, 11, 19, 33, 57, 209, 627

631 : 1, 631

323 : 1, 17, 19, 323

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,627,631,323, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

627:3x 11x 19

631:631

323:17x 19

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

3x 19 = 57

Therefore, the value for common factors is 57.

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 = 82041662142/(1x57)

LCM = 82041662142/57

LCM = 1439327406

Thus, we can understand that the LCM of 642,627,631,323 is 1439327406.
