Given numbers are 521,387,521,169

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

The LCM of 521,387,521,169 is 34074963.

Find LCM of 521,387,521,169 with Prime Factorization

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

521 x 1 x 387 x 1 x 169 = 34074963

Therefore, the lowest common multiple of 521,387,521,169 is 34074963.

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.

521 x 387 x 521 x 169 = 17753055723

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.

521 : 1, 521

387 : 1, 3, 9, 43, 129, 387

521 : 1, 521

169 : 1, 13, 169

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 521,387,521,169, is 1.

Now, the common factors can be found like this.

521:521

387:3x 3x 43

521:521

169:13x 13

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 = 17753055723/(1x521)

LCM = 17753055723/521

LCM = 34074963

Thus, we can understand that the LCM of 521,387,521,169 is 34074963.
