Given numbers are 168,781,121,473,664

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

The LCM of 168,781,121,473,664 is 5151094872.

Find LCM of 168,781,121,473,664 with Prime Factorization

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

2 x 2 x 2 x 11 x 21 x 71 x 11 x 43 x 83 = 5151094872

Therefore, the lowest common multiple of 168,781,121,473,664 is 5151094872.

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.

168 x 781 x 121 x 473 x 664 = 4986259836096

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.

168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168

781 : 1, 11, 71, 781

121 : 1, 11, 121

473 : 1, 11, 43, 473

664 : 1, 2, 4, 8, 83, 166, 332, 664

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 168,781,121,473,664, is 1.

Now, the common factors can be found like this.

168:2x 2x 2x 3x 7

781:11x 71

121:11x 11

473:11x 43

664:2x 2x 2x 83

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 11x 11 = 968

Therefore, the value for common factors is 968.

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 = 4986259836096/(1x968)

LCM = 4986259836096/968

LCM = 5151094872

Thus, we can understand that the LCM of 168,781,121,473,664 is 5151094872.
