Given numbers are 646,635,214,969

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

The LCM of 646,635,214,969 is 131677410.

Find LCM of 646,635,214,969 with Prime Factorization

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

2 x 17 x 19 x 1 x 635 x 107 x 3 = 131677410

Therefore, the lowest common multiple of 646,635,214,969 is 131677410.

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 635 x 214 x 969 = 85063606860

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

635 : 1, 5, 127, 635

214 : 1, 2, 107, 214

969 : 1, 3, 17, 19, 51, 57, 323, 969

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,635,214,969, is 1.

Now, the common factors can be found like this.

646:2x 17x 19

635:5x 127

214:2x 107

969:3x 17x 19

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

2x 17x 19 = 646

Therefore, the value for common factors is 646.

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 = 85063606860/(1x646)

LCM = 85063606860/646

LCM = 131677410

Thus, we can understand that the LCM of 646,635,214,969 is 131677410.
