Given numbers are 249,728,161,842

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

The LCM of 249,728,161,842 is 1755256776.

Find LCM of 249,728,161,842 with Prime Factorization

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

2 x 7 x 249 x 52 x 23 x 421 = 1755256776

Therefore, the lowest common multiple of 249,728,161,842 is 1755256776.

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.

249 x 728 x 161 x 842 = 24573594864

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.

249 : 1, 3, 83, 249

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

161 : 1, 7, 23, 161

842 : 1, 2, 421, 842

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 249,728,161,842, is 1.

Now, the common factors can be found like this.

249:3x 83

728:2x 2x 2x 7x 13

161:7x 23

842:2x 421

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 = 24573594864/(1x14)

LCM = 24573594864/14

LCM = 1755256776

Thus, we can understand that the LCM of 249,728,161,842 is 1755256776.
