Given numbers are 221,277,169,520

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

The LCM of 221,277,169,520 is 31832840.

Find LCM of 221,277,169,520 with Prime Factorization

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

13 x 17 x 277 x 13 x 40 = 31832840

Therefore, the lowest common multiple of 221,277,169,520 is 31832840.

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 277 x 169 x 520 = 5379749960

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

277 : 1, 277

169 : 1, 13, 169

520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,277,169,520, is 1.

Now, the common factors can be found like this.

221:13x 17

277:277

169:13x 13

520:2x 2x 2x 5x 13

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 = 5379749960/(1x169)

LCM = 5379749960/169

LCM = 31832840

Thus, we can understand that the LCM of 221,277,169,520 is 31832840.
