Given numbers are 326,163,672,780

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

The LCM of 326,163,672,780 is 7119840.

Find LCM of 326,163,672,780 with Prime Factorization

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

2 x 2 x 3 x 163 x 1 x 1 x 56 x 65 = 7119840

Therefore, the lowest common multiple of 326,163,672,780 is 7119840.

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.

326 x 163 x 672 x 780 = 27852814080

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.

326 : 1, 2, 163, 326

163 : 1, 163

672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 326,163,672,780, is 1.

Now, the common factors can be found like this.

326:2x 163

163:163

672:2x 2x 2x 2x 2x 3x 7

780:2x 2x 3x 5x 13

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 2x 3x 163 = 3912

Therefore, the value for common factors is 3912.

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 = 27852814080/(1x3912)

LCM = 27852814080/3912

LCM = 7119840

Thus, we can understand that the LCM of 326,163,672,780 is 7119840.

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