Given numbers are 606,681,145,642

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

The LCM of 606,681,145,642 is 2134274430.

Find LCM of 606,681,145,642 with Prime Factorization

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

2 x 3 x 101 x 227 x 145 x 107 = 2134274430

Therefore, the lowest common multiple of 606,681,145,642 is 2134274430.

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.

606 x 681 x 145 x 642 = 38416939740

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.

606 : 1, 2, 3, 6, 101, 202, 303, 606

681 : 1, 3, 227, 681

145 : 1, 5, 29, 145

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 606,681,145,642, is 1.

Now, the common factors can be found like this.

606:2x 3x 101

681:3x 227

145:5x 29

642:2x 3x 107

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

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 38416939740/(1x18)

LCM = 38416939740/18

LCM = 2134274430

Thus, we can understand that the LCM of 606,681,145,642 is 2134274430.
