Given numbers are 170,840,637,155,655

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

The LCM of 170,840,637,155,655 is 5277188280.

Find LCM of 170,840,637,155,655 with Prime Factorization

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

2 x 5 x 7 x 17 x 12 x 91 x 31 x 131 = 5277188280

Therefore, the lowest common multiple of 170,840,637,155,655 is 5277188280.

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.

170 x 840 x 637 x 155 x 655 = 9235079490000

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.

170 : 1, 2, 5, 10, 17, 34, 85, 170

840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840

637 : 1, 7, 13, 49, 91, 637

155 : 1, 5, 31, 155

655 : 1, 5, 131, 655

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 170,840,637,155,655, is 1.

Now, the common factors can be found like this.

170:2x 5x 17

840:2x 2x 2x 3x 5x 7

637:7x 7x 13

155:5x 31

655:5x 131

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 5x 5x 5x 7 = 1750

Therefore, the value for common factors is 1750.

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 = 9235079490000/(1x1750)

LCM = 9235079490000/1750

LCM = 5277188280

Thus, we can understand that the LCM of 170,840,637,155,655 is 5277188280.
