Given numbers are 788,161,221,856

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

The LCM of 788,161,221,856 is 6000095192.

Find LCM of 788,161,221,856 with Prime Factorization

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

2 x 2 x 197 x 161 x 221 x 214 = 6000095192

Therefore, the lowest common multiple of 788,161,221,856 is 6000095192.

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.

788 x 161 x 221 x 856 = 24000380768

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.

788 : 1, 2, 4, 197, 394, 788

161 : 1, 7, 23, 161

221 : 1, 13, 17, 221

856 : 1, 2, 4, 8, 107, 214, 428, 856

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 788,161,221,856, is 1.

Now, the common factors can be found like this.

788:2x 2x 197

161:7x 23

221:13x 17

856:2x 2x 2x 107

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 = 24000380768/(1x4)

LCM = 24000380768/4

LCM = 6000095192

Thus, we can understand that the LCM of 788,161,221,856 is 6000095192.
