Given numbers are 995,793,455,721,720
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 995,793,455,721,720 is 81920769840.
Find LCM of 995,793,455,721,720 with Prime Factorization
| 5 | 995, 793, 455, 721, 720 |
| 7 | 199, 793, 91, 721, 144 |
| 13 | 199, 793, 13, 103, 144 |
| 199, 61, 1, 103, 144 |
Multiply the prime numbers at the bottom and the left side.
5 x 7 x 13 x 199 x 61 x 1 x 103 x 144 = 81920769840
Therefore, the lowest common multiple of 995,793,455,721,720 is 81920769840.
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.
995 x 793 x 455 x 721 x 720 = 186369751386000
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.
995 : 1, 5, 199, 995
793 : 1, 13, 61, 793
455 : 1, 5, 7, 13, 35, 65, 91, 455
721 : 1, 7, 103, 721
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 995,793,455,721,720, is 1.
Now, the common factors can be found like this.
995:5x 199
793:13x 61
455:5x 7x 13
721:7x 103
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.
5x 5x 7x 13 = 2275
Therefore, the value for common factors is 2275.
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 = 186369751386000/(1x2275)
LCM = 186369751386000/2275
LCM = 81920769840
Thus, we can understand that the LCM of 995,793,455,721,720 is 81920769840.
