Given numbers are 221,559,533,655

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

The LCM of 221,559,533,655 is 255203065.

Find LCM of 221,559,533,655 with Prime Factorization

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

13 x 17 x 43 x 41 x 655 = 255203065

Therefore, the lowest common multiple of 221,559,533,655 is 255203065.

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 559 x 533 x 655 = 43129317985

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

559 : 1, 13, 43, 559

533 : 1, 13, 41, 533

655 : 1, 5, 131, 655

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,559,533,655, is 1.

Now, the common factors can be found like this.

221:13x 17

559:13x 43

533:13x 41

655:5x 131

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

13x 13 = 169

Therefore, the value for common factors is 169.

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 = 43129317985/(1x169)

LCM = 43129317985/169

LCM = 255203065

Thus, we can understand that the LCM of 221,559,533,655 is 255203065.
