Given numbers are 847,418,990,336,245

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

The LCM of 847,418,990,336,245 is 81108720.

Find LCM of 847,418,990,336,245 with Prime Factorization

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

2 x 3 x 5 x 7 x 11 x 11 x 19 x 3 x 8 x 7 = 81108720

Therefore, the lowest common multiple of 847,418,990,336,245 is 81108720.

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.

847 x 418 x 990 x 336 x 245 = 28853616052800

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.

847 : 1, 7, 11, 77, 121, 847

418 : 1, 2, 11, 19, 22, 38, 209, 418

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

336 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 42, 48, 56, 84, 112, 168, 336

245 : 1, 5, 7, 35, 49, 245

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 847,418,990,336,245, is 1.

Now, the common factors can be found like this.

847:7x 11x 11

418:2x 11x 19

990:2x 3x 3x 5x 11

336:2x 2x 2x 2x 3x 7

245:5x 7x 7

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 3x 5x 7x 7x 11x 11 = 355740

Therefore, the value for common factors is 355740.

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 = 28853616052800/(1x355740)

LCM = 28853616052800/355740

LCM = 81108720

Thus, we can understand that the LCM of 847,418,990,336,245 is 81108720.
