Calculate the LCM of 605,647,297,306,989

Given numbers are 605,647,297,306,989

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

The LCM of 605,647,297,306,989 is 355384619370.

Find LCM of 605,647,297,306,989 with Prime Factorization


3 605, 647, 297, 306, 989
3 605, 647, 99, 102, 989
11 605, 647, 33, 34, 989
55, 647, 3, 34, 989

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

3 x 3 x 11 x 55 x 647 x 3 x 34 x 989 = 355384619370

Therefore, the lowest common multiple of 605,647,297,306,989 is 355384619370.

LCM Formula to Find Lowest Common Multiple of 605,647,297,306,989

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.

605 x 647 x 297 x 306 x 989 = 35183077317630

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.

605 : 1, 5, 11, 55, 121, 605

647 : 1, 647

297 : 1, 3, 9, 11, 27, 33, 99, 297

306 : 1, 2, 3, 6, 9, 17, 18, 34, 51, 102, 153, 306

989 : 1, 23, 43, 989

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 605,647,297,306,989, is 1.

Now, the common factors can be found like this.

605:5x 11x 11

647:647

297:3x 3x 3x 11

306:2x 3x 3x 17

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.

3x 3x 11 = 99

Therefore, the value for common factors is 99.

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 = 35183077317630/(1x99)

LCM = 35183077317630/99

LCM = 355384619370

Thus, we can understand that the LCM of 605,647,297,306,989 is 355384619370.
