Given numbers are 172,532,121,985

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

The LCM of 172,532,121,985 is 2726476060.

Find LCM of 172,532,121,985 with Prime Factorization

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

2 x 2 x 43 x 133 x 121 x 985 = 2726476060

Therefore, the lowest common multiple of 172,532,121,985 is 2726476060.

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 532 x 121 x 985 = 10905904240

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

532 : 1, 2, 4, 7, 14, 19, 28, 38, 76, 133, 266, 532

121 : 1, 11, 121

985 : 1, 5, 197, 985

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 172,532,121,985, is 1.

Now, the common factors can be found like this.

172:2x 2x 43

532:2x 2x 7x 19

121:11x 11

985:5x 197

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 = 10905904240/(1x4)

LCM = 10905904240/4

LCM = 2726476060

Thus, we can understand that the LCM of 172,532,121,985 is 2726476060.
