Given numbers are 644,118,707,149

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

The LCM of 644,118,707,149 is 571801804.

Find LCM of 644,118,707,149 with Prime Factorization

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

2 x 7 x 46 x 59 x 101 x 149 = 571801804

Therefore, the lowest common multiple of 644,118,707,149 is 571801804.

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.

644 x 118 x 707 x 149 = 8005225256

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.

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

118 : 1, 2, 59, 118

707 : 1, 7, 101, 707

149 : 1, 149

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 644,118,707,149, is 1.

Now, the common factors can be found like this.

644:2x 2x 7x 23

118:2x 59

707:7x 101

149:149

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

2x 7 = 14

Therefore, the value for common factors is 14.

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 = 8005225256/(1x14)

LCM = 8005225256/14

LCM = 571801804

Thus, we can understand that the LCM of 644,118,707,149 is 571801804.
