Given numbers are 646,669,266,470

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

The LCM of 646,669,266,470 is 710926230.

Find LCM of 646,669,266,470 with Prime Factorization

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

2 x 19 x 17 x 669 x 7 x 235 = 710926230

Therefore, the lowest common multiple of 646,669,266,470 is 710926230.

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 669 x 266 x 470 = 54030393480

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

669 : 1, 3, 223, 669

266 : 1, 2, 7, 14, 19, 38, 133, 266

470 : 1, 2, 5, 10, 47, 94, 235, 470

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,669,266,470, is 1.

Now, the common factors can be found like this.

646:2x 17x 19

669:3x 223

266:2x 7x 19

470:2x 5x 47

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 19 = 76

Therefore, the value for common factors is 76.

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 = 54030393480/(1x76)

LCM = 54030393480/76

LCM = 710926230

Thus, we can understand that the LCM of 646,669,266,470 is 710926230.
