Given numbers are 220,286,397,66

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

The LCM of 220,286,397,66 is 3406260.

Find LCM of 220,286,397,66 with Prime Factorization

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

2 x 11 x 10 x 13 x 397 x 3 = 3406260

Therefore, the lowest common multiple of 220,286,397,66 is 3406260.

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.

220 x 286 x 397 x 66 = 1648629840

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.

220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220

286 : 1, 2, 11, 13, 22, 26, 143, 286

397 : 1, 397

66 : 1, 2, 3, 6, 11, 22, 33, 66

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 220,286,397,66, is 1.

Now, the common factors can be found like this.

220:2x 2x 5x 11

286:2x 11x 13

397:397

66:2x 3x 11

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 11x 11 = 484

Therefore, the value for common factors is 484.

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 = 1648629840/(1x484)

LCM = 1648629840/484

LCM = 3406260

Thus, we can understand that the LCM of 220,286,397,66 is 3406260.
