Given numbers are 657,660,873,778,528

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

The LCM of 657,660,873,778,528 is 21815711280.

Find LCM of 657,660,873,778,528 with Prime Factorization

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

2 x 2 x 3 x 3 x 11 x 73 x 5 x 97 x 389 x 4 = 21815711280

Therefore, the lowest common multiple of 657,660,873,778,528 is 21815711280.

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.

657 x 660 x 873 x 778 x 528 = 155502390003840

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.

657 : 1, 3, 9, 73, 219, 657

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

873 : 1, 3, 9, 97, 291, 873

778 : 1, 2, 389, 778

528 : 1, 2, 3, 4, 6, 8, 11, 12, 16, 22, 24, 33, 44, 48, 66, 88, 132, 176, 264, 528

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 657,660,873,778,528, is 1.

Now, the common factors can be found like this.

657:3x 3x 73

660:2x 2x 3x 5x 11

873:3x 3x 97

778:2x 389

528:2x 2x 2x 2x 3x 11

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 3x 3x 11 = 7128

Therefore, the value for common factors is 7128.

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 = 155502390003840/(1x7128)

LCM = 155502390003840/7128

LCM = 21815711280

Thus, we can understand that the LCM of 657,660,873,778,528 is 21815711280.
