Calculate the LCM of 826,845,839,247,691

Given numbers are 826,845,839,247,691

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

The LCM of 826,845,839,247,691 is 7688300781070.

Find LCM of 826,845,839,247,691 with Prime Factorization


13 826, 845, 839, 247, 691
826, 65, 839, 19, 691

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

13 x 826 x 65 x 839 x 19 x 691 = 7688300781070

Therefore, the lowest common multiple of 826,845,839,247,691 is 7688300781070.

LCM Formula to Find Lowest Common Multiple of 826,845,839,247,691

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.

826 x 845 x 839 x 247 x 691 = 99947910153910

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.

826 : 1, 2, 7, 14, 59, 118, 413, 826

845 : 1, 5, 13, 65, 169, 845

839 : 1, 839

247 : 1, 13, 19, 247

691 : 1, 691

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 826,845,839,247,691, is 1.

Now, the common factors can be found like this.

826:2x 7x 59

845:5x 13x 13

839:839

247:13x 19

691:691

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

13 = 13

Therefore, the value for common factors is 13.

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 = 99947910153910/(1x13)

LCM = 99947910153910/13

LCM = 7688300781070

Thus, we can understand that the LCM of 826,845,839,247,691 is 7688300781070.
