Given numbers are 644,836,912,388

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

The LCM of 644,836,912,388 is 156669744.

Find LCM of 644,836,912,388 with Prime Factorization

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

2 x 2 x 19 x 161 x 11 x 12 x 97 = 156669744

Therefore, the lowest common multiple of 644,836,912,388 is 156669744.

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 836 x 912 x 388 = 190510408704

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

836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836

912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912

388 : 1, 2, 4, 97, 194, 388

4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 644,836,912,388, is 4.

Now, the common factors can be found like this.

644:2x 2x 7x 23

836:2x 2x 11x 19

912:2x 2x 2x 2x 3x 19

388:2x 2x 97

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 2x 19 = 304

Therefore, the value for common factors is 304.

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 = 190510408704/(4x304)

LCM = 190510408704/1216

LCM = 156669744

Thus, we can understand that the LCM of 644,836,912,388 is 156669744.
