Calculate the LCM of 688,660,977,185

Given numbers are 688,660,977,185

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

The LCM of 688,660,977,185 is 4103634480.

Find LCM of 688,660,977,185 with Prime Factorization


2 688, 660, 977, 185
2 344, 330, 977, 185
5 172, 165, 977, 185
172, 33, 977, 37

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

2 x 2 x 5 x 172 x 33 x 977 x 37 = 4103634480

Therefore, the lowest common multiple of 688,660,977,185 is 4103634480.

LCM Formula to Find Lowest Common Multiple of 688,660,977,185

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.

688 x 660 x 977 x 185 = 82072689600

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.

688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688

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

977 : 1, 977

185 : 1, 5, 37, 185

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 688,660,977,185, is 1.

Now, the common factors can be found like this.

688:2x 2x 2x 2x 43

660:2x 2x 3x 5x 11

977:977

185:5x 37

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 5 = 20

Therefore, the value for common factors is 20.

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 = 82072689600/(1x20)

LCM = 82072689600/20

LCM = 4103634480

Thus, we can understand that the LCM of 688,660,977,185 is 4103634480.
