Given numbers are 138,205,814,779

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

The LCM of 138,205,814,779 is 218766570.

Find LCM of 138,205,814,779 with Prime Factorization

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

2 x 41 x 69 x 5 x 407 x 19 = 218766570

Therefore, the lowest common multiple of 138,205,814,779 is 218766570.

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 205 x 814 x 779 = 17938858740

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

205 : 1, 5, 41, 205

814 : 1, 2, 11, 22, 37, 74, 407, 814

779 : 1, 19, 41, 779

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 138,205,814,779, is 1.

Now, the common factors can be found like this.

138:2x 3x 23

205:5x 41

814:2x 11x 37

779:19x 41

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

2x 41 = 82

Therefore, the value for common factors is 82.

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 = 17938858740/(1x82)

LCM = 17938858740/82

LCM = 218766570

Thus, we can understand that the LCM of 138,205,814,779 is 218766570.
