Given numbers are 660,656,177,288,772

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

The LCM of 660,656,177,288,772 is 7395173280.

Find LCM of 660,656,177,288,772 with Prime Factorization

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

2 x 2 x 2 x 2 x 3 x 55 x 41 x 59 x 6 x 193 = 7395173280

Therefore, the lowest common multiple of 660,656,177,288,772 is 7395173280.

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 656 x 177 x 288 x 772 = 17038479237120

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

656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656

177 : 1, 3, 59, 177

288 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144, 288

772 : 1, 2, 4, 193, 386, 772

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 660,656,177,288,772, is 1.

Now, the common factors can be found like this.

660:2x 2x 3x 5x 11

656:2x 2x 2x 2x 41

177:3x 59

288:2x 2x 2x 2x 2x 3x 3

772:2x 2x 193

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 2x 2x 2x 2x 3x 3 = 2304

Therefore, the value for common factors is 2304.

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 = 17038479237120/(1x2304)

LCM = 17038479237120/2304

LCM = 7395173280

Thus, we can understand that the LCM of 660,656,177,288,772 is 7395173280.
