Given numbers are 621,302,565,195

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

The LCM of 621,302,565,195 is 1377495990.

Find LCM of 621,302,565,195 with Prime Factorization

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

3 x 5 x 207 x 302 x 113 x 13 = 1377495990

Therefore, the lowest common multiple of 621,302,565,195 is 1377495990.

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.

621 x 302 x 565 x 195 = 20662439850

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.

621 : 1, 3, 9, 23, 27, 69, 207, 621

302 : 1, 2, 151, 302

565 : 1, 5, 113, 565

195 : 1, 3, 5, 13, 15, 39, 65, 195

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 621,302,565,195, is 1.

Now, the common factors can be found like this.

621:3x 3x 3x 23

302:2x 151

565:5x 113

195:3x 5x 13

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

3x 5 = 15

Therefore, the value for common factors is 15.

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 = 20662439850/(1x15)

LCM = 20662439850/15

LCM = 1377495990

Thus, we can understand that the LCM of 621,302,565,195 is 1377495990.
