Given numbers are 946,731,135,781

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

The LCM of 946,731,135,781 is 154145970.

Find LCM of 946,731,135,781 with Prime Factorization

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

11 x 43 x 2 x 17 x 135 x 71 = 154145970

Therefore, the lowest common multiple of 946,731,135,781 is 154145970.

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.

946 x 731 x 135 x 781 = 72911043810

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.

946 : 1, 2, 11, 22, 43, 86, 473, 946

731 : 1, 17, 43, 731

135 : 1, 3, 5, 9, 15, 27, 45, 135

781 : 1, 11, 71, 781

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 946,731,135,781, is 1.

Now, the common factors can be found like this.

946:2x 11x 43

731:17x 43

135:3x 3x 3x 5

781:11x 71

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

11x 43 = 473

Therefore, the value for common factors is 473.

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 = 72911043810/(1x473)

LCM = 72911043810/473

LCM = 154145970

Thus, we can understand that the LCM of 946,731,135,781 is 154145970.
