Given numbers are 138,786,671,611

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

The LCM of 138,786,671,611 is 7411636518.

Find LCM of 138,786,671,611 with Prime Factorization

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

2 x 3 x 23 x 131 x 671 x 611 = 7411636518

Therefore, the lowest common multiple of 138,786,671,611 is 7411636518.

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 786 x 671 x 611 = 44469819108

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

786 : 1, 2, 3, 6, 131, 262, 393, 786

671 : 1, 11, 61, 671

611 : 1, 13, 47, 611

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 138,786,671,611, is 1.

Now, the common factors can be found like this.

138:2x 3x 23

786:2x 3x 131

671:11x 61

611:13x 47

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 44469819108/(1x6)

LCM = 44469819108/6

LCM = 7411636518

Thus, we can understand that the LCM of 138,786,671,611 is 7411636518.
