Calculate the LCM of 834,451,656,123

Given numbers are 834,451,656,123

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

The LCM of 834,451,656,123 is 3009072.

Find LCM of 834,451,656,123 with Prime Factorization


2 834, 451, 656, 123
3 417, 451, 328, 123
41 139, 451, 328, 41
139, 11, 8, 1

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

2 x 3 x 41 x 139 x 11 x 8 x 1 = 3009072

Therefore, the lowest common multiple of 834,451,656,123 is 3009072.

LCM Formula to Find Lowest Common Multiple of 834,451,656,123

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.

834 x 451 x 656 x 123 = 30349500192

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.

834 : 1, 2, 3, 6, 139, 278, 417, 834

451 : 1, 11, 41, 451

656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656

123 : 1, 3, 41, 123

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 834,451,656,123, is 1.

Now, the common factors can be found like this.

834:2x 3x 139

451:11x 41

656:2x 2x 2x 2x 41

123:3x 41

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

2x 3x 41x 41 = 10086

Therefore, the value for common factors is 10086.

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 = 30349500192/(1x10086)

LCM = 30349500192/10086

LCM = 3009072

Thus, we can understand that the LCM of 834,451,656,123 is 3009072.
