Calculate the LCM of 169,138,419,591,646

Given numbers are 169,138,419,591,646

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

The LCM of 169,138,419,591,646 is 621796914258.

Find LCM of 169,138,419,591,646 with Prime Factorization


2 169, 138, 419, 591, 646
3 169, 69, 419, 591, 323
169, 23, 419, 197, 323

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

2 x 3 x 169 x 23 x 419 x 197 x 323 = 621796914258

Therefore, the lowest common multiple of 169,138,419,591,646 is 621796914258.

LCM Formula to Find Lowest Common Multiple of 169,138,419,591,646

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.

169 x 138 x 419 x 591 x 646 = 3730781485548

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.

169 : 1, 13, 169

138 : 1, 2, 3, 6, 23, 46, 69, 138

419 : 1, 419

591 : 1, 3, 197, 591

646 : 1, 2, 17, 19, 34, 38, 323, 646

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 169,138,419,591,646, is 1.

Now, the common factors can be found like this.

169:13x 13

138:2x 3x 23

419:419

591:3x 197

646:2x 17x 19

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 3730781485548/(1x6)

LCM = 3730781485548/6

LCM = 621796914258

Thus, we can understand that the LCM of 169,138,419,591,646 is 621796914258.
