Given numbers are 621,202,397,808

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

The LCM of 621,202,397,808 is 199201896.

Find LCM of 621,202,397,808 with Prime Factorization

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

2 x 101 x 621 x 1 x 397 x 4 = 199201896

Therefore, the lowest common multiple of 621,202,397,808 is 199201896.

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 202 x 397 x 808 = 40238782992

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

202 : 1, 2, 101, 202

397 : 1, 397

808 : 1, 2, 4, 8, 101, 202, 404, 808

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 621,202,397,808, is 1.

Now, the common factors can be found like this.

621:3x 3x 3x 23

202:2x 101

397:397

808:2x 2x 2x 101

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

2x 101 = 202

Therefore, the value for common factors is 202.

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 = 40238782992/(1x202)

LCM = 40238782992/202

LCM = 199201896

Thus, we can understand that the LCM of 621,202,397,808 is 199201896.
