Given numbers are 920,214,996,781,731

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

The LCM of 920,214,996,781,731 is 13993919231160.

Find LCM of 920,214,996,781,731 with Prime Factorization

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

2 x 2 x 230 x 107 x 249 x 781 x 731 = 13993919231160

Therefore, the lowest common multiple of 920,214,996,781,731 is 13993919231160.

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.

920 x 214 x 996 x 781 x 731 = 111951353849280

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.

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

214 : 1, 2, 107, 214

996 : 1, 2, 3, 4, 6, 12, 83, 166, 249, 332, 498, 996

781 : 1, 11, 71, 781

731 : 1, 17, 43, 731

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 920,214,996,781,731, is 1.

Now, the common factors can be found like this.

920:2x 2x 2x 5x 23

214:2x 107

996:2x 2x 3x 83

781:11x 71

731:17x 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 2x 2 = 8

Therefore, the value for common factors is 8.

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 = 111951353849280/(1x8)

LCM = 111951353849280/8

LCM = 13993919231160

Thus, we can understand that the LCM of 920,214,996,781,731 is 13993919231160.
