Find LCM of 494,420,297,460 with Prime Factorization
2 | 494, 420, 297, 460 |
2 | 247, 210, 297, 230 |
3 | 247, 105, 297, 115 |
5 | 247, 35, 99, 115 |
247, 7, 99, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 247 x 7 x 99 x 23 = 236215980
Therefore, the lowest common multiple of 494,420,297,460 is 236215980.
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.
494 x 420 x 297 x 460 = 28345917600
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.
494 : 1, 2, 13, 19, 26, 38, 247, 494
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
297 : 1, 3, 9, 11, 27, 33, 99, 297
460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 494,420,297,460, is 1.
Now, the common factors can be found like this.
494:2x 13x 19
420:2x 2x 3x 5x 7
297:3x 3x 3x 11
460:2x 2x 5x 23
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 5 = 120
Therefore, the value for common factors is 120.
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 = 28345917600/(1x120)
LCM = 28345917600/120
LCM = 236215980
Thus, we can understand that the LCM of 494,420,297,460 is 236215980.
