Calculate the LCM of 843,744,317,989

Given numbers are 843,744,317,989

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

The LCM of 843,744,317,989 is 65544281832.

Find LCM of 843,744,317,989 with Prime Factorization


3 843, 744, 317, 989
281, 248, 317, 989

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

3 x 281 x 248 x 317 x 989 = 65544281832

Therefore, the lowest common multiple of 843,744,317,989 is 65544281832.

LCM Formula to Find Lowest Common Multiple of 843,744,317,989

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.

843 x 744 x 317 x 989 = 196632845496

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.

843 : 1, 3, 281, 843

744 : 1, 2, 3, 4, 6, 8, 12, 24, 31, 62, 93, 124, 186, 248, 372, 744

317 : 1, 317

989 : 1, 23, 43, 989

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 843,744,317,989, is 1.

Now, the common factors can be found like this.

843:3x 281

744:2x 2x 2x 3x 31

317:317

989:23x 43

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 = 196632845496/(1x3)

LCM = 196632845496/3

LCM = 65544281832

Thus, we can understand that the LCM of 843,744,317,989 is 65544281832.
