Given numbers are 660,828,458,691

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

The LCM of 660,828,458,691 is 7206204060.

Find LCM of 660,828,458,691 with Prime Factorization

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

2 x 2 x 3 x 55 x 69 x 229 x 691 = 7206204060

Therefore, the lowest common multiple of 660,828,458,691 is 7206204060.

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.

660 x 828 x 458 x 691 = 172948897440

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.

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

828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828

458 : 1, 2, 229, 458

691 : 1, 691

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 660,828,458,691, is 1.

Now, the common factors can be found like this.

660:2x 2x 3x 5x 11

828:2x 2x 3x 3x 23

458:2x 229

691:691

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 3 = 24

Therefore, the value for common factors is 24.

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 = 172948897440/(1x24)

LCM = 172948897440/24

LCM = 7206204060

Thus, we can understand that the LCM of 660,828,458,691 is 7206204060.
