The LCM of 775,138,274,961,465 is 454216650.
Find LCM of 775,138,274,961,465 with Prime Factorization
| 2 | 775, 138, 274, 961, 465 |
| 3 | 775, 69, 137, 961, 465 |
| 5 | 775, 23, 137, 961, 155 |
| 31 | 31, 23, 137, 961, 155 |
| 1, 23, 137, 31, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 31 x 1 x 23 x 137 x 31 x 5 = 454216650
Therefore, the lowest common multiple of 775,138,274,961,465 is 454216650.
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.
775 x 138 x 274 x 961 x 465 = 13095066019500
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.
775 : 1, 5, 25, 31, 155, 775
138 : 1, 2, 3, 6, 23, 46, 69, 138
274 : 1, 2, 137, 274
961 : 1, 31, 961
465 : 1, 3, 5, 15, 31, 93, 155, 465
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 775,138,274,961,465, is 1.
Now, the common factors can be found like this.
775:5x 5x 31
138:2x 3x 23
274:2x 137
961:31x 31
465:3x 5x 31
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 5x 31x 31 = 28830
Therefore, the value for common factors is 28830.
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 = 13095066019500/(1x28830)
LCM = 13095066019500/28830
LCM = 454216650
Thus, we can understand that the LCM of 775,138,274,961,465 is 454216650.
