Calculate the LCM of 786,898,671,138

Given numbers are 786,898,671,138

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

The LCM of 786,898,671,138 is 5446521762.

Find LCM of 786,898,671,138 with Prime Factorization


2 786, 898, 671, 138
3 393, 449, 671, 69
131, 449, 671, 23

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

2 x 3 x 131 x 449 x 671 x 23 = 5446521762

Therefore, the lowest common multiple of 786,898,671,138 is 5446521762.

LCM Formula to Find Lowest Common Multiple of 786,898,671,138

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.

786 x 898 x 671 x 138 = 65358261144

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.

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

898 : 1, 2, 449, 898

671 : 1, 11, 61, 671

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 786,898,671,138, is 1.

Now, the common factors can be found like this.

786:2x 3x 131

898:2x 449

671:11x 61

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 2x 3 = 12

Therefore, the value for common factors is 12.

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 = 65358261144/(1x12)

LCM = 65358261144/12

LCM = 5446521762

Thus, we can understand that the LCM of 786,898,671,138 is 5446521762.
