Given numbers are 290,836,209,520,230

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

The LCM of 290,836,209,520,230 is 72489560.

Find LCM of 290,836,209,520,230 with Prime Factorization

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

2 x 2 x 5 x 11 x 19 x 29 x 1 x 1 x 26 x 23 = 72489560

Therefore, the lowest common multiple of 290,836,209,520,230 is 72489560.

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.

290 x 836 x 209 x 520 x 230 = 6060127216000

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.

290 : 1, 2, 5, 10, 29, 58, 145, 290

836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836

209 : 1, 11, 19, 209

520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520

230 : 1, 2, 5, 10, 23, 46, 115, 230

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 290,836,209,520,230, is 1.

Now, the common factors can be found like this.

290:2x 5x 29

836:2x 2x 11x 19

209:11x 19

520:2x 2x 2x 5x 13

230:2x 5x 23

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 2x 5x 5x 11x 19 = 83600

Therefore, the value for common factors is 83600.

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 = 6060127216000/(1x83600)

LCM = 6060127216000/83600

LCM = 72489560

Thus, we can understand that the LCM of 290,836,209,520,230 is 72489560.
