Calculate the LCM of 486,686,484,836

Given numbers are 486,686,484,836

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

The LCM of 486,686,484,836 is 766477404.

Find LCM of 486,686,484,836 with Prime Factorization


2 486, 686, 484, 836
2 243, 343, 242, 418
11 243, 343, 121, 209
243, 343, 11, 19

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

2 x 2 x 11 x 243 x 343 x 11 x 19 = 766477404

Therefore, the lowest common multiple of 486,686,484,836 is 766477404.

LCM Formula to Find Lowest Common Multiple of 486,686,484,836

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.

486 x 686 x 484 x 836 = 134900023104

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.

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

686 : 1, 2, 7, 14, 49, 98, 343, 686

484 : 1, 2, 4, 11, 22, 44, 121, 242, 484

836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 486,686,484,836, is 2.

Now, the common factors can be found like this.

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

686:2x 7x 7x 7

484:2x 2x 11x 11

836:2x 2x 11x 19

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 11 = 88

Therefore, the value for common factors is 88.

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 = 134900023104/(2x88)

LCM = 134900023104/176

LCM = 766477404

Thus, we can understand that the LCM of 486,686,484,836 is 766477404.
