Calculate the LCM of 689,365,981,340

Given numbers are 689,365,981,340

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

The LCM of 689,365,981,340 is 16776061380.

Find LCM of 689,365,981,340 with Prime Factorization


5 689, 365, 981, 340
689, 73, 981, 68

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

5 x 689 x 73 x 981 x 68 = 16776061380

Therefore, the lowest common multiple of 689,365,981,340 is 16776061380.

LCM Formula to Find Lowest Common Multiple of 689,365,981,340

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.

689 x 365 x 981 x 340 = 83880306900

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.

689 : 1, 13, 53, 689

365 : 1, 5, 73, 365

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

340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,365,981,340, is 1.

Now, the common factors can be found like this.

689:13x 53

365:5x 73

981:3x 3x 109

340:2x 2x 5x 17

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

5 = 5

Therefore, the value for common factors is 5.

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 = 83880306900/(1x5)

LCM = 83880306900/5

LCM = 16776061380

Thus, we can understand that the LCM of 689,365,981,340 is 16776061380.
