Find LCM of 546,455,769,720 with Prime Factorization
| 2 | 546, 455, 769, 720 |
| 3 | 273, 455, 769, 360 |
| 5 | 91, 455, 769, 120 |
| 7 | 91, 91, 769, 24 |
| 13 | 13, 13, 769, 24 |
| 1, 1, 769, 24 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 13 x 1 x 1 x 769 x 24 = 50384880
Therefore, the lowest common multiple of 546,455,769,720 is 50384880.
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.
546 x 455 x 769 x 720 = 137550722400
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.
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
455 : 1, 5, 7, 13, 35, 65, 91, 455
769 : 1, 769
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 546,455,769,720, is 1.
Now, the common factors can be found like this.
546:2x 3x 7x 13
455:5x 7x 13
769:769
720:2x 2x 2x 2x 3x 3x 5
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 5x 7x 13 = 2730
Therefore, the value for common factors is 2730.
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 = 137550722400/(1x2730)
LCM = 137550722400/2730
LCM = 50384880
Thus, we can understand that the LCM of 546,455,769,720 is 50384880.
