Given numbers are 643,220,572,197,924

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

The LCM of 643,220,572,197,924 is 7607860260.

Find LCM of 643,220,572,197,924 with Prime Factorization

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

2 x 2 x 11 x 643 x 5 x 13 x 197 x 21 = 7607860260

Therefore, the lowest common multiple of 643,220,572,197,924 is 7607860260.

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 220 x 572 x 197 x 924 = 14728817463360

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

220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220

572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572

197 : 1, 197

924 : 1, 2, 3, 4, 6, 7, 11, 12, 14, 21, 22, 28, 33, 42, 44, 66, 77, 84, 132, 154, 231, 308, 462, 924

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,220,572,197,924, is 1.

Now, the common factors can be found like this.

643:643

220:2x 2x 5x 11

572:2x 2x 11x 13

197:197

924:2x 2x 3x 7x 11

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

2x 2x 2x 2x 11x 11 = 1936

Therefore, the value for common factors is 1936.

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 = 14728817463360/(1x1936)

LCM = 14728817463360/1936

LCM = 7607860260

Thus, we can understand that the LCM of 643,220,572,197,924 is 7607860260.
