Given numbers are 845,422,428,136

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

The LCM of 845,422,428,136 is 2594548840.

Find LCM of 845,422,428,136 with Prime Factorization

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

2 x 2 x 845 x 211 x 107 x 34 = 2594548840

Therefore, the lowest common multiple of 845,422,428,136 is 2594548840.

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.

845 x 422 x 428 x 136 = 20756390720

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.

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

422 : 1, 2, 211, 422

428 : 1, 2, 4, 107, 214, 428

136 : 1, 2, 4, 8, 17, 34, 68, 136

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 845,422,428,136, is 1.

Now, the common factors can be found like this.

845:5x 13x 13

422:2x 211

428:2x 2x 107

136:2x 2x 2x 17

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 2 = 8

Therefore, the value for common factors is 8.

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 = 20756390720/(1x8)

LCM = 20756390720/8

LCM = 2594548840

Thus, we can understand that the LCM of 845,422,428,136 is 2594548840.
