Given numbers are 451,685,511,274,720
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 451,685,511,274,720 is 22732673040.
Find LCM of 451,685,511,274,720 with Prime Factorization
| 2 | 451, 685, 511, 274, 720 |
| 5 | 451, 685, 511, 137, 360 |
| 137 | 451, 137, 511, 137, 72 |
| 451, 1, 511, 1, 72 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 137 x 451 x 1 x 511 x 1 x 72 = 22732673040
Therefore, the lowest common multiple of 451,685,511,274,720 is 22732673040.
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.
451 x 685 x 511 x 274 x 720 = 31143762064800
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.
451 : 1, 11, 41, 451
685 : 1, 5, 137, 685
511 : 1, 7, 73, 511
274 : 1, 2, 137, 274
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 451,685,511,274,720, is 1.
Now, the common factors can be found like this.
451:11x 41
685:5x 137
511:7x 73
274:2x 137
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 5x 137 = 1370
Therefore, the value for common factors is 1370.
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 = 31143762064800/(1x1370)
LCM = 31143762064800/1370
LCM = 22732673040
Thus, we can understand that the LCM of 451,685,511,274,720 is 22732673040.
