Given numbers are 217,124,992,856

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

The LCM of 217,124,992,856 is 743008.

Find LCM of 217,124,992,856 with Prime Factorization

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

2 x 2 x 2 x 31 x 7 x 1 x 4 x 107 = 743008

Therefore, the lowest common multiple of 217,124,992,856 is 743008.

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.

217 x 124 x 992 x 856 = 22848982016

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.

217 : 1, 7, 31, 217

124 : 1, 2, 4, 31, 62, 124

992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992

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 217,124,992,856, is 1.

Now, the common factors can be found like this.

217:7x 31

124:2x 2x 31

992:2x 2x 2x 2x 2x 31

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 2x 2x 2x 2x 31x 31 = 30752

Therefore, the value for common factors is 30752.

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 = 22848982016/(1x30752)

LCM = 22848982016/30752

LCM = 743008

Thus, we can understand that the LCM of 217,124,992,856 is 743008.
