Find LCM of 424,747,218,392,245 with Prime Factorization
| 2 | 424, 747, 218, 392, 245 |
| 2 | 212, 747, 109, 196, 245 |
| 2 | 106, 747, 109, 98, 245 |
| 7 | 53, 747, 109, 49, 245 |
| 7 | 53, 747, 109, 7, 35 |
| 53, 747, 109, 1, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 7 x 53 x 747 x 109 x 1 x 5 = 8458221240
Therefore, the lowest common multiple of 424,747,218,392,245 is 8458221240.
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.
424 x 747 x 218 x 392 x 245 = 6631245452160
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.
424 : 1, 2, 4, 8, 53, 106, 212, 424
747 : 1, 3, 9, 83, 249, 747
218 : 1, 2, 109, 218
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
245 : 1, 5, 7, 35, 49, 245
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 424,747,218,392,245, is 1.
Now, the common factors can be found like this.
424:2x 2x 2x 53
747:3x 3x 83
218:2x 109
392:2x 2x 2x 7x 7
245:5x 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 2x 2x 2x 7x 7 = 784
Therefore, the value for common factors is 784.
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 = 6631245452160/(1x784)
LCM = 6631245452160/784
LCM = 8458221240
Thus, we can understand that the LCM of 424,747,218,392,245 is 8458221240.
