Given numbers are 138,109,763,731

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

The LCM of 138,109,763,731 is 76969914.

Find LCM of 138,109,763,731 with Prime Factorization

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

109 x 138 x 1 x 7 x 731 = 76969914

Therefore, the lowest common multiple of 138,109,763,731 is 76969914.

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.

138 x 109 x 763 x 731 = 8389720626

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.

138 : 1, 2, 3, 6, 23, 46, 69, 138

109 : 1, 109

763 : 1, 7, 109, 763

731 : 1, 17, 43, 731

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 138,109,763,731, is 1.

Now, the common factors can be found like this.

138:2x 3x 23

109:109

763:7x 109

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.

109 = 109

Therefore, the value for common factors is 109.

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 = 8389720626/(1x109)

LCM = 8389720626/109

LCM = 76969914

Thus, we can understand that the LCM of 138,109,763,731 is 76969914.
