Given numbers are 178,325,217,221

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

The LCM of 178,325,217,221 is 213408650.

Find LCM of 178,325,217,221 with Prime Factorization

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

13 x 178 x 25 x 217 x 17 = 213408650

Therefore, the lowest common multiple of 178,325,217,221 is 213408650.

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.

178 x 325 x 217 x 221 = 2774312450

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.

178 : 1, 2, 89, 178

325 : 1, 5, 13, 25, 65, 325

217 : 1, 7, 31, 217

221 : 1, 13, 17, 221

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 178,325,217,221, is 1.

Now, the common factors can be found like this.

178:2x 89

325:5x 5x 13

217:7x 31

221:13x 17

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

13 = 13

Therefore, the value for common factors is 13.

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 = 2774312450/(1x13)

LCM = 2774312450/13

LCM = 213408650

Thus, we can understand that the LCM of 178,325,217,221 is 213408650.
