Calculate the LCM of 609,989,645,683

Given numbers are 609,989,645,683

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

The LCM of 609,989,645,683 is 2056857915.

Find LCM of 609,989,645,683 with Prime Factorization


3 609, 989, 645, 683
43 203, 989, 215, 683
203, 23, 5, 683

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

3 x 43 x 203 x 23 x 5 x 683 = 2056857915

Therefore, the lowest common multiple of 609,989,645,683 is 2056857915.

LCM Formula to Find Lowest Common Multiple of 609,989,645,683

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.

609 x 989 x 645 x 683 = 265334671035

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.

609 : 1, 3, 7, 21, 29, 87, 203, 609

989 : 1, 23, 43, 989

645 : 1, 3, 5, 15, 43, 129, 215, 645

683 : 1, 683

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 609,989,645,683, is 1.

Now, the common factors can be found like this.

609:3x 7x 29

989:23x 43

645:3x 5x 43

683:683

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

3x 43 = 129

Therefore, the value for common factors is 129.

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 = 265334671035/(1x129)

LCM = 265334671035/129

LCM = 2056857915

Thus, we can understand that the LCM of 609,989,645,683 is 2056857915.
