Given numbers are 172,763,473,981

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

The LCM of 172,763,473,981 is 12992364.

Find LCM of 172,763,473,981 with Prime Factorization

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

43 x 109 x 4 x 7 x 11 x 9 = 12992364

Therefore, the lowest common multiple of 172,763,473,981 is 12992364.

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 763 x 473 x 981 = 60895210068

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

763 : 1, 7, 109, 763

473 : 1, 11, 43, 473

981 : 1, 3, 9, 109, 327, 981

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 172,763,473,981, is 1.

Now, the common factors can be found like this.

172:2x 2x 43

763:7x 109

473:11x 43

981:3x 3x 109

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

43x 109 = 4687

Therefore, the value for common factors is 4687.

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 = 60895210068/(1x4687)

LCM = 60895210068/4687

LCM = 12992364

Thus, we can understand that the LCM of 172,763,473,981 is 12992364.
