Given numbers are 822,777,161,272,857
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 822,777,161,272,857 is 570714817008.
Find LCM of 822,777,161,272,857 with Prime Factorization
| 2 | 822, 777, 161, 272, 857 |
| 3 | 411, 777, 161, 136, 857 |
| 7 | 137, 259, 161, 136, 857 |
| 137, 37, 23, 136, 857 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 137 x 37 x 23 x 136 x 857 = 570714817008
Therefore, the lowest common multiple of 822,777,161,272,857 is 570714817008.
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.
822 x 777 x 161 x 272 x 857 = 23970022314336
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.
822 : 1, 2, 3, 6, 137, 274, 411, 822
777 : 1, 3, 7, 21, 37, 111, 259, 777
161 : 1, 7, 23, 161
272 : 1, 2, 4, 8, 16, 17, 34, 68, 136, 272
857 : 1, 857
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 822,777,161,272,857, is 1.
Now, the common factors can be found like this.
822:2x 3x 137
777:3x 7x 37
161:7x 23
272:2x 2x 2x 2x 17
857:857
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 7 = 42
Therefore, the value for common factors is 42.
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 = 23970022314336/(1x42)
LCM = 23970022314336/42
LCM = 570714817008
Thus, we can understand that the LCM of 822,777,161,272,857 is 570714817008.
