The LCM of 427,485,320,880 is 145794880.
Find LCM of 427,485,320,880 with Prime Factorization
| 2 | 427, 485, 320, 880 |
| 2 | 427, 485, 160, 440 |
| 2 | 427, 485, 80, 220 |
| 2 | 427, 485, 40, 110 |
| 5 | 427, 485, 20, 55 |
| 427, 97, 4, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 5 x 427 x 97 x 4 x 11 = 145794880
Therefore, the lowest common multiple of 427,485,320,880 is 145794880.
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.
427 x 485 x 320 x 880 = 58317952000
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.
427 : 1, 7, 61, 427
485 : 1, 5, 97, 485
320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 427,485,320,880, is 1.
Now, the common factors can be found like this.
427:7x 61
485:5x 97
320:2x 2x 2x 2x 2x 2x 5
880:2x 2x 2x 2x 5x 11
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 2x 5x 5 = 400
Therefore, the value for common factors is 400.
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 = 58317952000/(1x400)
LCM = 58317952000/400
LCM = 145794880
Thus, we can understand that the LCM of 427,485,320,880 is 145794880.
