Calculate the LCM of 437,981,389,693

Given numbers are 437,981,389,693

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

The LCM of 437,981,389,693 is 12840761241.

Find LCM of 437,981,389,693 with Prime Factorization


3 437, 981, 389, 693
3 437, 327, 389, 231
437, 109, 389, 77

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

3 x 3 x 437 x 109 x 389 x 77 = 12840761241

Therefore, the lowest common multiple of 437,981,389,693 is 12840761241.

LCM Formula to Find Lowest Common Multiple of 437,981,389,693

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.

437 x 981 x 389 x 693 = 115566851169

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.

437 : 1, 19, 23, 437

981 : 1, 3, 9, 109, 327, 981

389 : 1, 389

693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 437,981,389,693, is 1.

Now, the common factors can be found like this.

437:19x 23

981:3x 3x 109

389:389

693:3x 3x 7x 11

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

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 115566851169/(1x9)

LCM = 115566851169/9

LCM = 12840761241

Thus, we can understand that the LCM of 437,981,389,693 is 12840761241.
