Given numbers are 252,821,291,222,210

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

The LCM of 252,821,291,222,210 is 3712676940.

Find LCM of 252,821,291,222,210 with Prime Factorization

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

2 x 3 x 7 x 6 x 821 x 97 x 37 x 5 = 3712676940

Therefore, the lowest common multiple of 252,821,291,222,210 is 3712676940.

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.

252 x 821 x 291 x 222 x 210 = 2806783766640

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.

252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252

821 : 1, 821

291 : 1, 3, 97, 291

222 : 1, 2, 3, 6, 37, 74, 111, 222

210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 252,821,291,222,210, is 1.

Now, the common factors can be found like this.

252:2x 2x 3x 3x 7

821:821

291:3x 97

222:2x 3x 37

210:2x 3x 5x 7

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 3x 3x 3x 7 = 756

Therefore, the value for common factors is 756.

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 = 2806783766640/(1x756)

LCM = 2806783766640/756

LCM = 3712676940

Thus, we can understand that the LCM of 252,821,291,222,210 is 3712676940.
