Find LCM of 308,856,986,677,749 with Prime Factorization
| 2 | 308, 856, 986, 677, 749 |
| 2 | 154, 428, 493, 677, 749 |
| 7 | 77, 214, 493, 677, 749 |
| 107 | 11, 214, 493, 677, 107 |
| 11, 2, 493, 677, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 107 x 11 x 2 x 493 x 677 x 1 = 21998855032
Therefore, the lowest common multiple of 308,856,986,677,749 is 21998855032.
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.
308 x 856 x 986 x 677 x 749 = 131817139351744
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.
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
856 : 1, 2, 4, 8, 107, 214, 428, 856
986 : 1, 2, 17, 29, 34, 58, 493, 986
677 : 1, 677
749 : 1, 7, 107, 749
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 308,856,986,677,749, is 1.
Now, the common factors can be found like this.
308:2x 2x 7x 11
856:2x 2x 2x 107
986:2x 17x 29
677:677
749:7x 107
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 107 = 5992
Therefore, the value for common factors is 5992.
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 = 131817139351744/(1x5992)
LCM = 131817139351744/5992
LCM = 21998855032
Thus, we can understand that the LCM of 308,856,986,677,749 is 21998855032.
