Calculate the LCM of 786,928,876,486

Given numbers are 786,928,876,486

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

The LCM of 786,928,876,486 is 2156494752.

Find LCM of 786,928,876,486 with Prime Factorization


2 786, 928, 876, 486
2 393, 464, 438, 243
3 393, 232, 219, 243
131, 232, 73, 81

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

2 x 2 x 3 x 131 x 232 x 73 x 81 = 2156494752

Therefore, the lowest common multiple of 786,928,876,486 is 2156494752.

LCM Formula to Find Lowest Common Multiple of 786,928,876,486

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 928 x 876 x 486 = 310535244288

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

928 : 1, 2, 4, 8, 16, 29, 32, 58, 116, 232, 464, 928

876 : 1, 2, 3, 4, 6, 12, 73, 146, 219, 292, 438, 876

486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 786,928,876,486, is 2.

Now, the common factors can be found like this.

786:2x 3x 131

928:2x 2x 2x 2x 2x 29

876:2x 2x 3x 73

486:2x 3x 3x 3x 3x 3

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 2x 3x 3 = 72

Therefore, the value for common factors is 72.

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 = 310535244288/(2x72)

LCM = 310535244288/144

LCM = 2156494752

Thus, we can understand that the LCM of 786,928,876,486 is 2156494752.
