Given numbers are 126,338,646

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

The LCM of 126,338,646 is 6877962.

Find LCM of 126,338,646 with Prime Factorization

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

2 x 63 x 169 x 323 = 6877962

Therefore, the lowest common multiple of 126,338,646 is 6877962.

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.

126 x 338 x 646 = 27511848

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.

126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126

338 : 1, 2, 13, 26, 169, 338

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

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 126,338,646, is 2.

Now, the common factors can be found like this.

126:2x 3x 3x 7

338:2x 13x 13

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.

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 = 27511848/(2x2)

LCM = 27511848/4

LCM = 6877962

Thus, we can understand that the LCM of 126,338,646 is 6877962.

Here are some samples of LCM of two or more Numbers calculations.
