Given numbers are 841,121,646,676

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

The LCM of 841,121,646,676 is 22219310828.

Find LCM of 841,121,646,676 with Prime Factorization

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

2 x 841 x 121 x 323 x 338 = 22219310828

Therefore, the lowest common multiple of 841,121,646,676 is 22219310828.

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.

841 x 121 x 646 x 676 = 44438621656

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.

841 : 1, 29, 841

121 : 1, 11, 121

646 : 1, 2, 17, 19, 34, 38, 323, 646

676 : 1, 2, 4, 13, 26, 52, 169, 338, 676

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 841,121,646,676, is 1.

Now, the common factors can be found like this.

841:29x 29

121:11x 11

646:2x 17x 19

676:2x 2x 13x 13

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

2 = 2

Therefore, the value for common factors is 2.

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 = 44438621656/(1x2)

LCM = 44438621656/2

LCM = 22219310828

Thus, we can understand that the LCM of 841,121,646,676 is 22219310828.
