Calculate the LCM of 921,839,908,678

Given numbers are 921,839,908,678

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

The LCM of 921,839,908,678 is 79284060276.

Find LCM of 921,839,908,678 with Prime Factorization


2 921, 839, 908, 678
3 921, 839, 454, 339
307, 839, 454, 113

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

2 x 3 x 307 x 839 x 454 x 113 = 79284060276

Therefore, the lowest common multiple of 921,839,908,678 is 79284060276.

LCM Formula to Find Lowest Common Multiple of 921,839,908,678

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.

921 x 839 x 908 x 678 = 475704361656

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.

921 : 1, 3, 307, 921

839 : 1, 839

908 : 1, 2, 4, 227, 454, 908

678 : 1, 2, 3, 6, 113, 226, 339, 678

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 921,839,908,678, is 1.

Now, the common factors can be found like this.

921:3x 307

839:839

908:2x 2x 227

678:2x 3x 113

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 475704361656/(1x6)

LCM = 475704361656/6

LCM = 79284060276

Thus, we can understand that the LCM of 921,839,908,678 is 79284060276.
