Given numbers are 997,878,988,816,639

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

The LCM of 997,878,988,816,639 is 18789983295408.

Find LCM of 997,878,988,816,639 with Prime Factorization

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

2 x 2 x 3 x 997 x 439 x 247 x 68 x 213 = 18789983295408

Therefore, the lowest common multiple of 997,878,988,816,639 is 18789983295408.

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.

997 x 878 x 988 x 816 x 639 = 450959599089792

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.

997 : 1, 997

878 : 1, 2, 439, 878

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

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

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 997,878,988,816,639, is 1.

Now, the common factors can be found like this.

997:997

878:2x 439

988:2x 2x 13x 19

816:2x 2x 2x 2x 3x 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 2x 2x 3 = 24

Therefore, the value for common factors is 24.

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 = 450959599089792/(1x24)

LCM = 450959599089792/24

LCM = 18789983295408

Thus, we can understand that the LCM of 997,878,988,816,639 is 18789983295408.
