Given numbers are 778,166,981,581

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

The LCM of 778,166,981,581 is 443429658.

Find LCM of 778,166,981,581 with Prime Factorization

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

2 x 83 x 389 x 1 x 981 x 7 = 443429658

Therefore, the lowest common multiple of 778,166,981,581 is 443429658.

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.

778 x 166 x 981 x 581 = 73609323228

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.

778 : 1, 2, 389, 778

166 : 1, 2, 83, 166

981 : 1, 3, 9, 109, 327, 981

581 : 1, 7, 83, 581

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 778,166,981,581, is 1.

Now, the common factors can be found like this.

778:2x 389

166:2x 83

981:3x 3x 109

581:7x 83

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

2x 83 = 166

Therefore, the value for common factors is 166.

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 = 73609323228/(1x166)

LCM = 73609323228/166

LCM = 443429658

Thus, we can understand that the LCM of 778,166,981,581 is 443429658.
