The LCM of 831,457,280,297,480 is 42108564960.
Find LCM of 831,457,280,297,480 with Prime Factorization
| 2 | 831, 457, 280, 297, 480 |
| 2 | 831, 457, 140, 297, 240 |
| 2 | 831, 457, 70, 297, 120 |
| 3 | 831, 457, 35, 297, 60 |
| 5 | 277, 457, 35, 99, 20 |
| 277, 457, 7, 99, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 277 x 457 x 7 x 99 x 4 = 42108564960
Therefore, the lowest common multiple of 831,457,280,297,480 is 42108564960.
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.
831 x 457 x 280 x 297 x 480 = 15159083385600
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.
831 : 1, 3, 277, 831
457 : 1, 457
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
297 : 1, 3, 9, 11, 27, 33, 99, 297
480 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 80, 96, 120, 160, 240, 480
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 831,457,280,297,480, is 1.
Now, the common factors can be found like this.
831:3x 277
457:457
280:2x 2x 2x 5x 7
297:3x 3x 3x 11
480:2x 2x 2x 2x 2x 3x 5
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 3x 3x 5 = 360
Therefore, the value for common factors is 360.
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 = 15159083385600/(1x360)
LCM = 15159083385600/360
LCM = 42108564960
Thus, we can understand that the LCM of 831,457,280,297,480 is 42108564960.
