Given numbers are 247,638,689,997

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

The LCM of 247,638,689,997 is 8327001826.

Find LCM of 247,638,689,997 with Prime Factorization

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

13 x 19 x 638 x 53 x 997 = 8327001826

Therefore, the lowest common multiple of 247,638,689,997 is 8327001826.

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.

247 x 638 x 689 x 997 = 108251023738

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.

247 : 1, 13, 19, 247

638 : 1, 2, 11, 22, 29, 58, 319, 638

689 : 1, 13, 53, 689

997 : 1, 997

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,638,689,997, is 1.

Now, the common factors can be found like this.

247:13x 19

638:2x 11x 29

689:13x 53

997:997

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

13 = 13

Therefore, the value for common factors is 13.

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 = 108251023738/(1x13)

LCM = 108251023738/13

LCM = 8327001826

Thus, we can understand that the LCM of 247,638,689,997 is 8327001826.
