Given numbers are 493,720,799,860
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 493,720,799,860 is 717374160.
Find LCM of 493,720,799,860 with Prime Factorization
| 2 | 493, 720, 799, 860 |
| 2 | 493, 360, 799, 430 |
| 5 | 493, 180, 799, 215 |
| 17 | 493, 36, 799, 43 |
| 29, 36, 47, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 17 x 29 x 36 x 47 x 43 = 717374160
Therefore, the lowest common multiple of 493,720,799,860 is 717374160.
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 720 x 799 x 860 = 243907214400
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
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
799 : 1, 17, 47, 799
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 493,720,799,860, is 1.
Now, the common factors can be found like this.
493:17x 29
720:2x 2x 2x 2x 3x 3x 5
799:17x 47
860:2x 2x 5x 43
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 5x 17 = 340
Therefore, the value for common factors is 340.
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 = 243907214400/(1x340)
LCM = 243907214400/340
LCM = 717374160
Thus, we can understand that the LCM of 493,720,799,860 is 717374160.
