Given numbers are 221,338,299,615

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

The LCM of 221,338,299,615 is 81277170.

Find LCM of 221,338,299,615 with Prime Factorization

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

13 x 17 x 26 x 23 x 615 = 81277170

Therefore, the lowest common multiple of 221,338,299,615 is 81277170.

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.

221 x 338 x 299 x 615 = 13735841730

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.

221 : 1, 13, 17, 221

338 : 1, 2, 13, 26, 169, 338

299 : 1, 13, 23, 299

615 : 1, 3, 5, 15, 41, 123, 205, 615

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,338,299,615, is 1.

Now, the common factors can be found like this.

221:13x 17

338:2x 13x 13

299:13x 23

615:3x 5x 41

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

13x 13 = 169

Therefore, the value for common factors is 169.

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 = 13735841730/(1x169)

LCM = 13735841730/169

LCM = 81277170

Thus, we can understand that the LCM of 221,338,299,615 is 81277170.
