Given numbers are 780,171,209,671,177

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

The LCM of 780,171,209,671,177 is 1760126940.

Find LCM of 780,171,209,671,177 with Prime Factorization

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

3 x 11 x 19 x 260 x 3 x 1 x 61 x 59 = 1760126940

Therefore, the lowest common multiple of 780,171,209,671,177 is 1760126940.

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.

780 x 171 x 209 x 671 x 177 = 3310798774140

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.

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

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

209 : 1, 11, 19, 209

671 : 1, 11, 61, 671

177 : 1, 3, 59, 177

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,171,209,671,177, is 1.

Now, the common factors can be found like this.

780:2x 2x 3x 5x 13

171:3x 3x 19

209:11x 19

671:11x 61

177:3x 59

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

3x 3x 11x 19 = 1881

Therefore, the value for common factors is 1881.

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 = 3310798774140/(1x1881)

LCM = 3310798774140/1881

LCM = 1760126940

Thus, we can understand that the LCM of 780,171,209,671,177 is 1760126940.
