Given numbers are 221,189,521,521

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

The LCM of 221,189,521,521 is 21761649.

Find LCM of 221,189,521,521 with Prime Factorization

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

521 x 221 x 189 x 1 x 1 = 21761649

Therefore, the lowest common multiple of 221,189,521,521 is 21761649.

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 189 x 521 x 521 = 11337819129

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

189 : 1, 3, 7, 9, 21, 27, 63, 189

521 : 1, 521

521 : 1, 521

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,189,521,521, is 1.

Now, the common factors can be found like this.

221:13x 17

189:3x 3x 3x 7

521:521

521:521

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

521 = 521

Therefore, the value for common factors is 521.

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 = 11337819129/(1x521)

LCM = 11337819129/521

LCM = 21761649

Thus, we can understand that the LCM of 221,189,521,521 is 21761649.
