Given numbers are 842,716,121,646

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

The LCM of 842,716,121,646 is 11781023188.

Find LCM of 842,716,121,646 with Prime Factorization

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

2 x 421 x 358 x 121 x 323 = 11781023188

Therefore, the lowest common multiple of 842,716,121,646 is 11781023188.

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 716 x 121 x 646 = 47124092752

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

716 : 1, 2, 4, 179, 358, 716

121 : 1, 11, 121

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 842,716,121,646, is 1.

Now, the common factors can be found like this.

842:2x 421

716:2x 2x 179

121:11x 11

646:2x 17x 19

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 = 47124092752/(1x4)

LCM = 47124092752/4

LCM = 11781023188

Thus, we can understand that the LCM of 842,716,121,646 is 11781023188.
