Given numbers are 221,228,174,842

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

The LCM of 221,228,174,842 is 615187092.

Find LCM of 221,228,174,842 with Prime Factorization

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

2 x 3 x 221 x 38 x 29 x 421 = 615187092

Therefore, the lowest common multiple of 221,228,174,842 is 615187092.

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 228 x 174 x 842 = 7382245104

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

228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228

174 : 1, 2, 3, 6, 29, 58, 87, 174

842 : 1, 2, 421, 842

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,228,174,842, is 1.

Now, the common factors can be found like this.

221:13x 17

228:2x 2x 3x 19

174:2x 3x 29

842:2x 421

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 3 = 12

Therefore, the value for common factors is 12.

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 = 7382245104/(1x12)

LCM = 7382245104/12

LCM = 615187092

Thus, we can understand that the LCM of 221,228,174,842 is 615187092.
