Given numbers are 642,101,149,707

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

The LCM of 642,101,149,707 is 67630206.

Find LCM of 642,101,149,707 with Prime Factorization

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

101 x 642 x 1 x 149 x 7 = 67630206

Therefore, the lowest common multiple of 642,101,149,707 is 67630206.

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 101 x 149 x 707 = 6830650806

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

101 : 1, 101

149 : 1, 149

707 : 1, 7, 101, 707

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,101,149,707, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

101:101

149:149

707:7x 101

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

101 = 101

Therefore, the value for common factors is 101.

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 = 6830650806/(1x101)

LCM = 6830650806/101

LCM = 67630206

Thus, we can understand that the LCM of 642,101,149,707 is 67630206.
