Given numbers are 646,209,551,212,109

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

The LCM of 646,209,551,212,109 is 2380978996.

Find LCM of 646,209,551,212,109 with Prime Factorization

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

2 x 19 x 17 x 11 x 29 x 106 x 109 = 2380978996

Therefore, the lowest common multiple of 646,209,551,212,109 is 2380978996.

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.

646 x 209 x 551 x 212 x 109 = 1719066835112

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.

646 : 1, 2, 17, 19, 34, 38, 323, 646

209 : 1, 11, 19, 209

551 : 1, 19, 29, 551

212 : 1, 2, 4, 53, 106, 212

109 : 1, 109

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,209,551,212,109, is 1.

Now, the common factors can be found like this.

646:2x 17x 19

209:11x 19

551:19x 29

212:2x 2x 53

109:109

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

2x 19x 19 = 722

Therefore, the value for common factors is 722.

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 = 1719066835112/(1x722)

LCM = 1719066835112/722

LCM = 2380978996

Thus, we can understand that the LCM of 646,209,551,212,109 is 2380978996.
