The LCM of 924,686,793,988 is 682173492.
Find LCM of 924,686,793,988 with Prime Factorization
| 2 | 924, 686, 793, 988 |
| 2 | 462, 343, 793, 494 |
| 7 | 231, 343, 793, 247 |
| 13 | 33, 49, 793, 247 |
| 33, 49, 61, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 13 x 33 x 49 x 61 x 19 = 682173492
Therefore, the lowest common multiple of 924,686,793,988 is 682173492.
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.
924 x 686 x 793 x 988 = 496622302176
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.
924 : 1, 2, 3, 4, 6, 7, 11, 12, 14, 21, 22, 28, 33, 42, 44, 66, 77, 84, 132, 154, 231, 308, 462, 924
686 : 1, 2, 7, 14, 49, 98, 343, 686
793 : 1, 13, 61, 793
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 924,686,793,988, is 1.
Now, the common factors can be found like this.
924:2x 2x 3x 7x 11
686:2x 7x 7x 7
793:13x 61
988:2x 2x 13x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 7x 13 = 728
Therefore, the value for common factors is 728.
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 = 496622302176/(1x728)
LCM = 496622302176/728
LCM = 682173492
Thus, we can understand that the LCM of 924,686,793,988 is 682173492.
