Given numbers are 136,247,613,988,646

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

The LCM of 136,247,613,988,646 is 20591896.

Find LCM of 136,247,613,988,646 with Prime Factorization

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

2 x 2 x 13 x 17 x 19 x 2 x 1 x 613 x 1 x 1 = 20591896

Therefore, the lowest common multiple of 136,247,613,988,646 is 20591896.

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.

136 x 247 x 613 x 988 x 646 = 13142736438208

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.

136 : 1, 2, 4, 8, 17, 34, 68, 136

247 : 1, 13, 19, 247

613 : 1, 613

988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988

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 136,247,613,988,646, is 1.

Now, the common factors can be found like this.

136:2x 2x 2x 17

247:13x 19

613:613

988:2x 2x 13x 19

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 2x 2x 13x 17x 19x 19 = 638248

Therefore, the value for common factors is 638248.

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 = 13142736438208/(1x638248)

LCM = 13142736438208/638248

LCM = 20591896

Thus, we can understand that the LCM of 136,247,613,988,646 is 20591896.
