Calculate the LCM of 969,399,987,219

Given numbers are 969,399,987,219

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

The LCM of 969,399,987,219 is 23272473.

Find LCM of 969,399,987,219 with Prime Factorization


3 969, 399, 987, 219
7 323, 133, 329, 73
19 323, 19, 47, 73
17, 1, 47, 73

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

3 x 7 x 19 x 17 x 1 x 47 x 73 = 23272473

Therefore, the lowest common multiple of 969,399,987,219 is 23272473.

LCM Formula to Find Lowest Common Multiple of 969,399,987,219

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.

969 x 399 x 987 x 219 = 83571450543

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.

969 : 1, 3, 17, 19, 51, 57, 323, 969

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

987 : 1, 3, 7, 21, 47, 141, 329, 987

219 : 1, 3, 73, 219

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 969,399,987,219, is 3.

Now, the common factors can be found like this.

969:3x 17x 19

399:3x 7x 19

987:3x 7x 47

219:3x 73

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 7x 19 = 1197

Therefore, the value for common factors is 1197.

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 = 83571450543/(3x1197)

LCM = 83571450543/3591

LCM = 23272473

Thus, we can understand that the LCM of 969,399,987,219 is 23272473.
