Given numbers are 687,337,658,136,639

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

The LCM of 687,337,658,136,639 is 2206485346968.

Find LCM of 687,337,658,136,639 with Prime Factorization

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

2 x 3 x 229 x 337 x 329 x 68 x 213 = 2206485346968

Therefore, the lowest common multiple of 687,337,658,136,639 is 2206485346968.

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.

687 x 337 x 658 x 136 x 639 = 13238912081808

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.

687 : 1, 3, 229, 687

337 : 1, 337

658 : 1, 2, 7, 14, 47, 94, 329, 658

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

639 : 1, 3, 9, 71, 213, 639

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 687,337,658,136,639, is 1.

Now, the common factors can be found like this.

687:3x 229

337:337

658:2x 7x 47

136:2x 2x 2x 17

639:3x 3x 71

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 = 13238912081808/(1x6)

LCM = 13238912081808/6

LCM = 2206485346968

Thus, we can understand that the LCM of 687,337,658,136,639 is 2206485346968.
