Given numbers are 770,731,386,138

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

The LCM of 770,731,386,138 is 7495739790.

Find LCM of 770,731,386,138 with Prime Factorization

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

2 x 385 x 731 x 193 x 69 = 7495739790

Therefore, the lowest common multiple of 770,731,386,138 is 7495739790.

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.

770 x 731 x 386 x 138 = 29982959160

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.

770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770

731 : 1, 17, 43, 731

386 : 1, 2, 193, 386

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 770,731,386,138, is 1.

Now, the common factors can be found like this.

770:2x 5x 7x 11

731:17x 43

386:2x 193

138:2x 3x 23

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 29982959160/(1x4)

LCM = 29982959160/4

LCM = 7495739790

Thus, we can understand that the LCM of 770,731,386,138 is 7495739790.
