Given numbers are 161,911,728,208

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

The LCM of 161,911,728,208 is 30507568.

Find LCM of 161,911,728,208 with Prime Factorization

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

2 x 2 x 2 x 7 x 13 x 23 x 911 x 1 x 2 = 30507568

Therefore, the lowest common multiple of 161,911,728,208 is 30507568.

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.

161 x 911 x 728 x 208 = 22209509504

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.

161 : 1, 7, 23, 161

911 : 1, 911

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

208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,911,728,208, is 1.

Now, the common factors can be found like this.

161:7x 23

911:911

728:2x 2x 2x 7x 13

208:2x 2x 2x 2x 13

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 2x 7x 13 = 728

Therefore, the value for common factors is 728.

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 = 22209509504/(1x728)

LCM = 22209509504/728

LCM = 30507568

Thus, we can understand that the LCM of 161,911,728,208 is 30507568.
