Calculate the LCM of 399,690,223

Given numbers are 399,690,223

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

The LCM of 399,690,223 is 20464710.

Find LCM of 399,690,223 with Prime Factorization


3 399, 690, 223
133, 230, 223

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

3 x 133 x 230 x 223 = 20464710

Therefore, the lowest common multiple of 399,690,223 is 20464710.

LCM Formula to Find Lowest Common Multiple of 399,690,223

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.

399 x 690 x 223 = 61394130

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.

399 : 1, 3, 7, 19, 21, 57, 133, 399

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

223 : 1, 223

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 399,690,223, is 1.

Now, the common factors can be found like this.

399:3x 7x 19

690:2x 3x 5x 23

223:223

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

3 = 3

Therefore, the value for common factors is 3.

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 = 61394130/(1x3)

LCM = 61394130/3

LCM = 20464710

Thus, we can understand that the LCM of 399,690,223 is 20464710.
