Find LCM of 720,546,215,466,440 with Prime Factorization
| 2 | 720, 546, 215, 466, 440 |
| 2 | 360, 273, 215, 233, 220 |
| 2 | 180, 273, 215, 233, 110 |
| 3 | 90, 273, 215, 233, 55 |
| 5 | 30, 91, 215, 233, 55 |
| 6, 91, 43, 233, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 6 x 91 x 43 x 233 x 11 = 7220893680
Therefore, the lowest common multiple of 720,546,215,466,440 is 7220893680.
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.
720 x 546 x 215 x 466 x 440 = 17330144832000
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.
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
215 : 1, 5, 43, 215
466 : 1, 2, 233, 466
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 720,546,215,466,440, is 1.
Now, the common factors can be found like this.
720:2x 2x 2x 2x 3x 3x 5
546:2x 3x 7x 13
215:5x 43
466:2x 233
440:2x 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 2x 3x 5x 5 = 2400
Therefore, the value for common factors is 2400.
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 = 17330144832000/(1x2400)
LCM = 17330144832000/2400
LCM = 7220893680
Thus, we can understand that the LCM of 720,546,215,466,440 is 7220893680.
