Given numbers are 507,643,642,953

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

The LCM of 507,643,642,953 is 66485295942.

Find LCM of 507,643,642,953 with Prime Factorization

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

3 x 169 x 643 x 214 x 953 = 66485295942

Therefore, the lowest common multiple of 507,643,642,953 is 66485295942.

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.

507 x 643 x 642 x 953 = 199455887826

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.

507 : 1, 3, 13, 39, 169, 507

643 : 1, 643

642 : 1, 2, 3, 6, 107, 214, 321, 642

953 : 1, 953

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 507,643,642,953, is 1.

Now, the common factors can be found like this.

507:3x 13x 13

643:643

642:2x 3x 107

953:953

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

3 = 3

Therefore, the value for common factors is 3.

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 = 199455887826/(1x3)

LCM = 199455887826/3

LCM = 66485295942

Thus, we can understand that the LCM of 507,643,642,953 is 66485295942.
