Given numbers are 708,411,128,660

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

The LCM of 708,411,128,660 is 170712960.

Find LCM of 708,411,128,660 with Prime Factorization

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

2 x 2 x 3 x 59 x 137 x 32 x 55 = 170712960

Therefore, the lowest common multiple of 708,411,128,660 is 170712960.

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.

708 x 411 x 128 x 660 = 24582666240

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.

708 : 1, 2, 3, 4, 6, 12, 59, 118, 177, 236, 354, 708

411 : 1, 3, 137, 411

128 : 1, 2, 4, 8, 16, 32, 64, 128

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 708,411,128,660, is 1.

Now, the common factors can be found like this.

708:2x 2x 3x 59

411:3x 137

128:2x 2x 2x 2x 2x 2x 2

660:2x 2x 3x 5x 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 2x 3x 3 = 144

Therefore, the value for common factors is 144.

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 = 24582666240/(1x144)

LCM = 24582666240/144

LCM = 170712960

Thus, we can understand that the LCM of 708,411,128,660 is 170712960.
