Given numbers are 138,427,253,791

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

The LCM of 138,427,253,791 is 73245018.

Find LCM of 138,427,253,791 with Prime Factorization

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

7 x 23 x 6 x 61 x 11 x 113 = 73245018

Therefore, the lowest common multiple of 138,427,253,791 is 73245018.

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 427 x 253 x 791 = 11792447898

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

427 : 1, 7, 61, 427

253 : 1, 11, 23, 253

791 : 1, 7, 113, 791

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 138,427,253,791, is 1.

Now, the common factors can be found like this.

138:2x 3x 23

427:7x 61

253:11x 23

791:7x 113

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

7x 23 = 161

Therefore, the value for common factors is 161.

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 = 11792447898/(1x161)

LCM = 11792447898/161

LCM = 73245018

Thus, we can understand that the LCM of 138,427,253,791 is 73245018.
