Given numbers are 415,778,764,785

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

The LCM of 415,778,764,785 is 19363805380.

Find LCM of 415,778,764,785 with Prime Factorization

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

2 x 5 x 83 x 389 x 382 x 157 = 19363805380

Therefore, the lowest common multiple of 415,778,764,785 is 19363805380.

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.

415 x 778 x 764 x 785 = 193638053800

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.

415 : 1, 5, 83, 415

778 : 1, 2, 389, 778

764 : 1, 2, 4, 191, 382, 764

785 : 1, 5, 157, 785

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 415,778,764,785, is 1.

Now, the common factors can be found like this.

415:5x 83

778:2x 389

764:2x 2x 191

785:5x 157

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 193638053800/(1x10)

LCM = 193638053800/10

LCM = 19363805380

Thus, we can understand that the LCM of 415,778,764,785 is 19363805380.
