Given numbers are 620,474,845,778

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

The LCM of 620,474,845,778 is 9659982540.

Find LCM of 620,474,845,778 with Prime Factorization

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

2 x 5 x 62 x 237 x 169 x 389 = 9659982540

Therefore, the lowest common multiple of 620,474,845,778 is 9659982540.

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 474 x 845 x 778 = 193199650800

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

474 : 1, 2, 3, 6, 79, 158, 237, 474

845 : 1, 5, 13, 65, 169, 845

778 : 1, 2, 389, 778

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,474,845,778, is 1.

Now, the common factors can be found like this.

620:2x 2x 5x 31

474:2x 3x 79

845:5x 13x 13

778:2x 389

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 5 = 20

Therefore, the value for common factors is 20.

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 = 193199650800/(1x20)

LCM = 193199650800/20

LCM = 9659982540

Thus, we can understand that the LCM of 620,474,845,778 is 9659982540.
