Given numbers are 842,426,442,869

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

The LCM of 842,426,442,869 is 34443219954.

Find LCM of 842,426,442,869 with Prime Factorization

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

2 x 421 x 213 x 221 x 869 = 34443219954

Therefore, the lowest common multiple of 842,426,442,869 is 34443219954.

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.

842 x 426 x 442 x 869 = 137772879816

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.

842 : 1, 2, 421, 842

426 : 1, 2, 3, 6, 71, 142, 213, 426

442 : 1, 2, 13, 17, 26, 34, 221, 442

869 : 1, 11, 79, 869

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 842,426,442,869, is 1.

Now, the common factors can be found like this.

842:2x 421

426:2x 3x 71

442:2x 13x 17

869:11x 79

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 137772879816/(1x4)

LCM = 137772879816/4

LCM = 34443219954

Thus, we can understand that the LCM of 842,426,442,869 is 34443219954.
