Given numbers are 172,564,221,161

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

The LCM of 172,564,221,161 is 862910412.

Find LCM of 172,564,221,161 with Prime Factorization

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

2 x 2 x 43 x 141 x 221 x 161 = 862910412

Therefore, the lowest common multiple of 172,564,221,161 is 862910412.

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.

172 x 564 x 221 x 161 = 3451641648

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.

172 : 1, 2, 4, 43, 86, 172

564 : 1, 2, 3, 4, 6, 12, 47, 94, 141, 188, 282, 564

221 : 1, 13, 17, 221

161 : 1, 7, 23, 161

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 172,564,221,161, is 1.

Now, the common factors can be found like this.

172:2x 2x 43

564:2x 2x 3x 47

221:13x 17

161:7x 23

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 3451641648/(1x4)

LCM = 3451641648/4

LCM = 862910412

Thus, we can understand that the LCM of 172,564,221,161 is 862910412.
