Given numbers are 172,107,436,340

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

The LCM of 172,107,436,340 is 170513060.

Find LCM of 172,107,436,340 with Prime Factorization

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

2 x 2 x 43 x 107 x 109 x 85 = 170513060

Therefore, the lowest common multiple of 172,107,436,340 is 170513060.

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 107 x 436 x 340 = 2728208960

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

107 : 1, 107

436 : 1, 2, 4, 109, 218, 436

340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 172,107,436,340, is 1.

Now, the common factors can be found like this.

172:2x 2x 43

107:107

436:2x 2x 109

340:2x 2x 5x 17

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

2x 2x 2x 2 = 16

Therefore, the value for common factors is 16.

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 = 2728208960/(1x16)

LCM = 2728208960/16

LCM = 170513060

Thus, we can understand that the LCM of 172,107,436,340 is 170513060.
