Given numbers are 643,231,436,652,212

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

The LCM of 643,231,436,652,212 is 559464991932.

Find LCM of 643,231,436,652,212 with Prime Factorization

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

2 x 2 x 643 x 231 x 109 x 163 x 53 = 559464991932

Therefore, the lowest common multiple of 643,231,436,652,212 is 559464991932.

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 231 x 436 x 652 x 212 = 8951439870912

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

231 : 1, 3, 7, 11, 21, 33, 77, 231

436 : 1, 2, 4, 109, 218, 436

652 : 1, 2, 4, 163, 326, 652

212 : 1, 2, 4, 53, 106, 212

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,231,436,652,212, is 1.

Now, the common factors can be found like this.

643:643

231:3x 7x 11

436:2x 2x 109

652:2x 2x 163

212:2x 2x 53

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 2 = 16

Therefore, the value for common factors is 16.

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 = 8951439870912/(1x16)

LCM = 8951439870912/16

LCM = 559464991932

Thus, we can understand that the LCM of 643,231,436,652,212 is 559464991932.
