Given numbers are 171,676,188,815

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

The LCM of 171,676,188,815 is 4427904780.

Find LCM of 171,676,188,815 with Prime Factorization

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

2 x 2 x 171 x 169 x 47 x 815 = 4427904780

Therefore, the lowest common multiple of 171,676,188,815 is 4427904780.

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.

171 x 676 x 188 x 815 = 17711619120

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.

171 : 1, 3, 9, 19, 57, 171

676 : 1, 2, 4, 13, 26, 52, 169, 338, 676

188 : 1, 2, 4, 47, 94, 188

815 : 1, 5, 163, 815

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 171,676,188,815, is 1.

Now, the common factors can be found like this.

171:3x 3x 19

676:2x 2x 13x 13

188:2x 2x 47

815:5x 163

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 17711619120/(1x4)

LCM = 17711619120/4

LCM = 4427904780

Thus, we can understand that the LCM of 171,676,188,815 is 4427904780.
