Given numbers are 642,614,418,533,661

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

The LCM of 642,614,418,533,661 is 14512704690198.

Find LCM of 642,614,418,533,661 with Prime Factorization

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

2 x 321 x 307 x 209 x 533 x 661 = 14512704690198

Therefore, the lowest common multiple of 642,614,418,533,661 is 14512704690198.

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.

642 x 614 x 418 x 533 x 661 = 58050818760792

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.

642 : 1, 2, 3, 6, 107, 214, 321, 642

614 : 1, 2, 307, 614

418 : 1, 2, 11, 19, 22, 38, 209, 418

533 : 1, 13, 41, 533

661 : 1, 661

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,614,418,533,661, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

614:2x 307

418:2x 11x 19

533:13x 41

661:661

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 58050818760792/(1x4)

LCM = 58050818760792/4

LCM = 14512704690198

Thus, we can understand that the LCM of 642,614,418,533,661 is 14512704690198.
