Given numbers are 642,666,380,559,614

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

The LCM of 642,666,380,559,614 is 2323602265140.

Find LCM of 642,666,380,559,614 with Prime Factorization

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

2 x 3 x 107 x 111 x 190 x 559 x 307 = 2323602265140

Therefore, the lowest common multiple of 642,666,380,559,614 is 2323602265140.

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 666 x 380 x 559 x 614 = 55766454363360

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

666 : 1, 2, 3, 6, 9, 18, 37, 74, 111, 222, 333, 666

380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380

559 : 1, 13, 43, 559

614 : 1, 2, 307, 614

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,666,380,559,614, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

666:2x 3x 3x 37

380:2x 2x 5x 19

559:13x 43

614:2x 307

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 3 = 24

Therefore, the value for common factors is 24.

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 = 55766454363360/(1x24)

LCM = 55766454363360/24

LCM = 2323602265140

Thus, we can understand that the LCM of 642,666,380,559,614 is 2323602265140.
