Given numbers are 385,209,779,621

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

The LCM of 385,209,779,621 is 186247215.

Find LCM of 385,209,779,621 with Prime Factorization

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

11 x 19 x 35 x 1 x 41 x 621 = 186247215

Therefore, the lowest common multiple of 385,209,779,621 is 186247215.

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.

385 x 209 x 779 x 621 = 38925667935

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.

385 : 1, 5, 7, 11, 35, 55, 77, 385

209 : 1, 11, 19, 209

779 : 1, 19, 41, 779

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 385,209,779,621, is 1.

Now, the common factors can be found like this.

385:5x 7x 11

209:11x 19

779:19x 41

621:3x 3x 3x 23

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

11x 19 = 209

Therefore, the value for common factors is 209.

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 = 38925667935/(1x209)

LCM = 38925667935/209

LCM = 186247215

Thus, we can understand that the LCM of 385,209,779,621 is 186247215.
