Find LCM of 493,551,420,882 with Prime Factorization
| 2 | 493, 551, 420, 882 |
| 3 | 493, 551, 210, 441 |
| 7 | 493, 551, 70, 147 |
| 29 | 493, 551, 10, 21 |
| 17, 19, 10, 21 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 29 x 17 x 19 x 10 x 21 = 82616940
Therefore, the lowest common multiple of 493,551,420,882 is 82616940.
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.
493 x 551 x 420 x 882 = 100627432920
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.
493 : 1, 17, 29, 493
551 : 1, 19, 29, 551
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
882 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 49, 63, 98, 126, 147, 294, 441, 882
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 493,551,420,882, is 1.
Now, the common factors can be found like this.
493:17x 29
551:19x 29
420:2x 2x 3x 5x 7
882:2x 3x 3x 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 3x 7x 29 = 1218
Therefore, the value for common factors is 1218.
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 = 100627432920/(1x1218)
LCM = 100627432920/1218
LCM = 82616940
Thus, we can understand that the LCM of 493,551,420,882 is 82616940.
