Given numbers are 791,442,404,161

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

The LCM of 791,442,404,161 is 1624343812.

Find LCM of 791,442,404,161 with Prime Factorization

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

2 x 7 x 113 x 221 x 202 x 23 = 1624343812

Therefore, the lowest common multiple of 791,442,404,161 is 1624343812.

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.

791 x 442 x 404 x 161 = 22740813368

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.

791 : 1, 7, 113, 791

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

404 : 1, 2, 4, 101, 202, 404

161 : 1, 7, 23, 161

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 791,442,404,161, is 1.

Now, the common factors can be found like this.

791:7x 113

442:2x 13x 17

404:2x 2x 101

161:7x 23

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

2x 7 = 14

Therefore, the value for common factors is 14.

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 = 22740813368/(1x14)

LCM = 22740813368/14

LCM = 1624343812

Thus, we can understand that the LCM of 791,442,404,161 is 1624343812.
