Given numbers are 221,689,538,260

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

The LCM of 221,689,538,260 is 63015940.

Find LCM of 221,689,538,260 with Prime Factorization

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

2 x 13 x 17 x 53 x 269 x 10 = 63015940

Therefore, the lowest common multiple of 221,689,538,260 is 63015940.

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 689 x 538 x 260 = 21299387720

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

689 : 1, 13, 53, 689

538 : 1, 2, 269, 538

260 : 1, 2, 4, 5, 10, 13, 20, 26, 52, 65, 130, 260

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,689,538,260, is 1.

Now, the common factors can be found like this.

221:13x 17

689:13x 53

538:2x 269

260:2x 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.

2x 13x 13 = 338

Therefore, the value for common factors is 338.

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 = 21299387720/(1x338)

LCM = 21299387720/338

LCM = 63015940

Thus, we can understand that the LCM of 221,689,538,260 is 63015940.
