The LCM of 977,990,387,720,229 is 76194510480.
Find LCM of 977,990,387,720,229 with Prime Factorization
| 2 | 977, 990, 387, 720, 229 |
| 3 | 977, 495, 387, 360, 229 |
| 3 | 977, 165, 129, 120, 229 |
| 5 | 977, 55, 43, 40, 229 |
| 977, 11, 43, 8, 229 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 977 x 11 x 43 x 8 x 229 = 76194510480
Therefore, the lowest common multiple of 977,990,387,720,229 is 76194510480.
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.
977 x 990 x 387 x 720 x 229 = 61717553488800
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.
977 : 1, 977
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
387 : 1, 3, 9, 43, 129, 387
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
229 : 1, 229
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 977,990,387,720,229, is 1.
Now, the common factors can be found like this.
977:977
990:2x 3x 3x 5x 11
387:3x 3x 43
720:2x 2x 2x 2x 3x 3x 5
229:229
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 3x 5 = 810
Therefore, the value for common factors is 810.
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 = 61717553488800/(1x810)
LCM = 61717553488800/810
LCM = 76194510480
Thus, we can understand that the LCM of 977,990,387,720,229 is 76194510480.
