Calculate the LCM of 306,997,422,646

Given numbers are 306,997,422,646

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

The LCM of 306,997,422,646 is 1223073738.

Find LCM of 306,997,422,646 with Prime Factorization


2 306, 997, 422, 646
17 153, 997, 211, 323
9, 997, 211, 19

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

2 x 17 x 9 x 997 x 211 x 19 = 1223073738

Therefore, the lowest common multiple of 306,997,422,646 is 1223073738.

LCM Formula to Find Lowest Common Multiple of 306,997,422,646

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.

306 x 997 x 422 x 646 = 83169014184

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.

306 : 1, 2, 3, 6, 9, 17, 18, 34, 51, 102, 153, 306

997 : 1, 997

422 : 1, 2, 211, 422

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 306,997,422,646, is 1.

Now, the common factors can be found like this.

306:2x 3x 3x 17

997:997

422:2x 211

646:2x 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 2x 17 = 68

Therefore, the value for common factors is 68.

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 = 83169014184/(1x68)

LCM = 83169014184/68

LCM = 1223073738

Thus, we can understand that the LCM of 306,997,422,646 is 1223073738.
