Given numbers are 172,781,269,392

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

The LCM of 172,781,269,392 is 3541260184.

Find LCM of 172,781,269,392 with Prime Factorization

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

2 x 2 x 43 x 781 x 269 x 98 = 3541260184

Therefore, the lowest common multiple of 172,781,269,392 is 3541260184.

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 781 x 269 x 392 = 14165040736

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

781 : 1, 11, 71, 781

269 : 1, 269

392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 172,781,269,392, is 1.

Now, the common factors can be found like this.

172:2x 2x 43

781:11x 71

269:269

392:2x 2x 2x 7x 7

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 = 14165040736/(1x4)

LCM = 14165040736/4

LCM = 3541260184

Thus, we can understand that the LCM of 172,781,269,392 is 3541260184.
