Given numbers are 650,646,778

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

The LCM of 650,646,778 is 81670550.

Find LCM of 650,646,778 with Prime Factorization

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

2 x 325 x 323 x 389 = 81670550

Therefore, the lowest common multiple of 650,646,778 is 81670550.

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.

650 x 646 x 778 = 326682200

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.

650 : 1, 2, 5, 10, 13, 25, 26, 50, 65, 130, 325, 650

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

778 : 1, 2, 389, 778

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 650,646,778, is 2.

Now, the common factors can be found like this.

650:2x 5x 5x 13

646:2x 17x 19

778:2x 389

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

2 = 2

Therefore, the value for common factors is 2.

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 = 326682200/(2x2)

LCM = 326682200/4

LCM = 81670550

Thus, we can understand that the LCM of 650,646,778 is 81670550.
