Given numbers are 889,244,257,220

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

The LCM of 889,244,257,220 is 3066107660.

Find LCM of 889,244,257,220 with Prime Factorization

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

2 x 2 x 889 x 61 x 257 x 55 = 3066107660

Therefore, the lowest common multiple of 889,244,257,220 is 3066107660.

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.

889 x 244 x 257 x 220 = 12264430640

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.

889 : 1, 7, 127, 889

244 : 1, 2, 4, 61, 122, 244

257 : 1, 257

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 889,244,257,220, is 1.

Now, the common factors can be found like this.

889:7x 127

244:2x 2x 61

257:257

220:2x 2x 5x 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 2 = 4

Therefore, the value for common factors is 4.

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 = 12264430640/(1x4)

LCM = 12264430640/4

LCM = 3066107660

Thus, we can understand that the LCM of 889,244,257,220 is 3066107660.
