Calculate the LCM of 399,872,673,198

Given numbers are 399,872,673,198

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

The LCM of 399,872,673,198 is 7727132952.

Find LCM of 399,872,673,198 with Prime Factorization


2 399, 872, 673, 198
3 399, 436, 673, 99
133, 436, 673, 33

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

2 x 3 x 133 x 436 x 673 x 33 = 7727132952

Therefore, the lowest common multiple of 399,872,673,198 is 7727132952.

LCM Formula to Find Lowest Common Multiple of 399,872,673,198

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 872 x 673 x 198 = 46362797712

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

872 : 1, 2, 4, 8, 109, 218, 436, 872

673 : 1, 673

198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 399,872,673,198, is 1.

Now, the common factors can be found like this.

399:3x 7x 19

872:2x 2x 2x 109

673:673

198:2x 3x 3x 11

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 46362797712/(1x6)

LCM = 46362797712/6

LCM = 7727132952

Thus, we can understand that the LCM of 399,872,673,198 is 7727132952.
