Given numbers are 780,654,474,177,458

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

The LCM of 780,654,474,177,458 is 90747712380.

Find LCM of 780,654,474,177,458 with Prime Factorization

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

2 x 3 x 130 x 109 x 79 x 59 x 229 = 90747712380

Therefore, the lowest common multiple of 780,654,474,177,458 is 90747712380.

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.

780 x 654 x 474 x 177 x 458 = 19601505874080

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.

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

654 : 1, 2, 3, 6, 109, 218, 327, 654

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

177 : 1, 3, 59, 177

458 : 1, 2, 229, 458

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,654,474,177,458, is 1.

Now, the common factors can be found like this.

780:2x 2x 3x 5x 13

654:2x 3x 109

474:2x 3x 79

177:3x 59

458:2x 229

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 3x 3x 3 = 216

Therefore, the value for common factors is 216.

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 = 19601505874080/(1x216)

LCM = 19601505874080/216

LCM = 90747712380

Thus, we can understand that the LCM of 780,654,474,177,458 is 90747712380.
