Given numbers are 620,755,532,912

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

The LCM of 620,755,532,912 is 149417520.

Find LCM of 620,755,532,912 with Prime Factorization

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

2 x 2 x 5 x 19 x 31 x 151 x 7 x 12 = 149417520

Therefore, the lowest common multiple of 620,755,532,912 is 149417520.

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.

620 x 755 x 532 x 912 = 227114630400

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.

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

755 : 1, 5, 151, 755

532 : 1, 2, 4, 7, 14, 19, 28, 38, 76, 133, 266, 532

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,755,532,912, is 1.

Now, the common factors can be found like this.

620:2x 2x 5x 31

755:5x 151

532:2x 2x 7x 19

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

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 5x 19 = 1520

Therefore, the value for common factors is 1520.

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 = 227114630400/(1x1520)

LCM = 227114630400/1520

LCM = 149417520

Thus, we can understand that the LCM of 620,755,532,912 is 149417520.
