Find LCM of 275,686,871,891,980 with Prime Factorization
| 2 | 275, 686, 871, 891, 980 |
| 5 | 275, 343, 871, 891, 490 |
| 7 | 55, 343, 871, 891, 98 |
| 7 | 55, 49, 871, 891, 14 |
| 11 | 55, 7, 871, 891, 2 |
| 5, 7, 871, 81, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 7 x 11 x 5 x 7 x 871 x 81 x 2 = 26618892300
Therefore, the lowest common multiple of 275,686,871,891,980 is 26618892300.
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.
275 x 686 x 871 x 891 x 980 = 143475829497000
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.
275 : 1, 5, 11, 25, 55, 275
686 : 1, 2, 7, 14, 49, 98, 343, 686
871 : 1, 13, 67, 871
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 275,686,871,891,980, is 1.
Now, the common factors can be found like this.
275:5x 5x 11
686:2x 7x 7x 7
871:13x 67
891:3x 3x 3x 3x 11
980:2x 2x 5x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 7x 7x 11 = 5390
Therefore, the value for common factors is 5390.
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 = 143475829497000/(1x5390)
LCM = 143475829497000/5390
LCM = 26618892300
Thus, we can understand that the LCM of 275,686,871,891,980 is 26618892300.
