Given numbers are 823,551,171,546
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 823,551,171,546 is 742788774.
Find LCM of 823,551,171,546 with Prime Factorization
| 3 | 823, 551, 171, 546 |
| 19 | 823, 551, 57, 182 |
| 823, 29, 3, 182 |
Multiply the prime numbers at the bottom and the left side.
3 x 19 x 823 x 29 x 3 x 182 = 742788774
Therefore, the lowest common multiple of 823,551,171,546 is 742788774.
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.
823 x 551 x 171 x 546 = 42338960118
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.
823 : 1, 823
551 : 1, 19, 29, 551
171 : 1, 3, 9, 19, 57, 171
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 823,551,171,546, is 1.
Now, the common factors can be found like this.
823:823
551:19x 29
171:3x 3x 19
546:2x 3x 7x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 19 = 57
Therefore, the value for common factors is 57.
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 = 42338960118/(1x57)
LCM = 42338960118/57
LCM = 742788774
Thus, we can understand that the LCM of 823,551,171,546 is 742788774.
