Given numbers are 638,690,379,318,348

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

The LCM of 638,690,379,318,348 is 8842699140.

Find LCM of 638,690,379,318,348 with Prime Factorization

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

2 x 3 x 29 x 11 x 115 x 379 x 53 x 2 = 8842699140

Therefore, the lowest common multiple of 638,690,379,318,348 is 8842699140.

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.

638 x 690 x 379 x 318 x 348 = 18463555804320

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.

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

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

379 : 1, 379

318 : 1, 2, 3, 6, 53, 106, 159, 318

348 : 1, 2, 3, 4, 6, 12, 29, 58, 87, 116, 174, 348

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,690,379,318,348, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

690:2x 3x 5x 23

379:379

318:2x 3x 53

348:2x 2x 3x 29

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 3x 3x 29 = 2088

Therefore, the value for common factors is 2088.

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 = 18463555804320/(1x2088)

LCM = 18463555804320/2088

LCM = 8842699140

Thus, we can understand that the LCM of 638,690,379,318,348 is 8842699140.
