Given numbers are 643,206,979,652

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

The LCM of 643,206,979,652 is 42274500532.

Find LCM of 643,206,979,652 with Prime Factorization

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

2 x 643 x 103 x 979 x 326 = 42274500532

Therefore, the lowest common multiple of 643,206,979,652 is 42274500532.

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.

643 x 206 x 979 x 652 = 84549001064

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.

643 : 1, 643

206 : 1, 2, 103, 206

979 : 1, 11, 89, 979

652 : 1, 2, 4, 163, 326, 652

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,206,979,652, is 1.

Now, the common factors can be found like this.

643:643

206:2x 103

979:11x 89

652:2x 2x 163

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

2 = 2

Therefore, the value for common factors is 2.

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 = 84549001064/(1x2)

LCM = 84549001064/2

LCM = 42274500532

Thus, we can understand that the LCM of 643,206,979,652 is 42274500532.
