Calculate the LCM of 671,781,816,209,187

Given numbers are 671,781,816,209,187

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

The LCM of 671,781,816,209,187 is 738626064.

Find LCM of 671,781,816,209,187 with Prime Factorization


11 671, 781, 816, 209, 187
17 61, 71, 816, 19, 17
61, 71, 48, 19, 1

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

11 x 17 x 61 x 71 x 48 x 19 x 1 = 738626064

Therefore, the lowest common multiple of 671,781,816,209,187 is 738626064.

LCM Formula to Find Lowest Common Multiple of 671,781,816,209,187

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.

671 x 781 x 816 x 209 x 187 = 16712891950128

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.

671 : 1, 11, 61, 671

781 : 1, 11, 71, 781

816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816

209 : 1, 11, 19, 209

187 : 1, 11, 17, 187

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 671,781,816,209,187, is 1.

Now, the common factors can be found like this.

671:11x 61

781:11x 71

816:2x 2x 2x 2x 3x 17

209:11x 19

187:11x 17

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

11x 11x 11x 17 = 22627

Therefore, the value for common factors is 22627.

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 = 16712891950128/(1x22627)

LCM = 16712891950128/22627

LCM = 738626064

Thus, we can understand that the LCM of 671,781,816,209,187 is 738626064.
