Given numbers are 277,723,420,800
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 277,723,420,800 is 1121517600.
Find LCM of 277,723,420,800 with Prime Factorization
| 2 | 277, 723, 420, 800 |
| 2 | 277, 723, 210, 400 |
| 3 | 277, 723, 105, 200 |
| 5 | 277, 241, 35, 200 |
| 277, 241, 7, 40 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 277 x 241 x 7 x 40 = 1121517600
Therefore, the lowest common multiple of 277,723,420,800 is 1121517600.
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.
277 x 723 x 420 x 800 = 67291056000
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.
277 : 1, 277
723 : 1, 3, 241, 723
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
800 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 277,723,420,800, is 1.
Now, the common factors can be found like this.
277:277
723:3x 241
420:2x 2x 3x 5x 7
800:2x 2x 2x 2x 2x 5x 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 2x 3x 5 = 60
Therefore, the value for common factors is 60.
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 = 67291056000/(1x60)
LCM = 67291056000/60
LCM = 1121517600
Thus, we can understand that the LCM of 277,723,420,800 is 1121517600.
