Given numbers are 138,287,713,977

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

The LCM of 138,287,713,977 is 1199546922.

Find LCM of 138,287,713,977 with Prime Factorization

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

23 x 6 x 287 x 31 x 977 = 1199546922

Therefore, the lowest common multiple of 138,287,713,977 is 1199546922.

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 287 x 713 x 977 = 27589579206

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

287 : 1, 7, 41, 287

713 : 1, 23, 31, 713

977 : 1, 977

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 138,287,713,977, is 1.

Now, the common factors can be found like this.

138:2x 3x 23

287:7x 41

713:23x 31

977:977

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

23 = 23

Therefore, the value for common factors is 23.

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 = 27589579206/(1x23)

LCM = 27589579206/23

LCM = 1199546922

Thus, we can understand that the LCM of 138,287,713,977 is 1199546922.
