Given numbers are 667,406,917,172

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

The LCM of 667,406,917,172 is 105201908.

Find LCM of 667,406,917,172 with Prime Factorization

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

2 x 7 x 29 x 23 x 1 x 131 x 86 = 105201908

Therefore, the lowest common multiple of 667,406,917,172 is 105201908.

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.

667 x 406 x 917 x 172 = 42711974648

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.

667 : 1, 23, 29, 667

406 : 1, 2, 7, 14, 29, 58, 203, 406

917 : 1, 7, 131, 917

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 667,406,917,172, is 1.

Now, the common factors can be found like this.

667:23x 29

406:2x 7x 29

917:7x 131

172:2x 2x 43

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

2x 7x 29 = 406

Therefore, the value for common factors is 406.

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 = 42711974648/(1x406)

LCM = 42711974648/406

LCM = 105201908

Thus, we can understand that the LCM of 667,406,917,172 is 105201908.
