Given numbers are 247,959,209,171
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 247,959,209,171 is 23450427.
Find LCM of 247,959,209,171 with Prime Factorization
19 | 247, 959, 209, 171 |
13, 959, 11, 9 |
Multiply the prime numbers at the bottom and the left side.
19 x 13 x 959 x 11 x 9 = 23450427
Therefore, the lowest common multiple of 247,959,209,171 is 23450427.
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.
247 x 959 x 209 x 171 = 8465604147
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.
247 : 1, 13, 19, 247
959 : 1, 7, 137, 959
209 : 1, 11, 19, 209
171 : 1, 3, 9, 19, 57, 171
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,959,209,171, is 1.
Now, the common factors can be found like this.
247:13x 19
959:7x 137
209:11x 19
171:3x 3x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
19x 19 = 361
Therefore, the value for common factors is 361.
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 = 8465604147/(1x361)
LCM = 8465604147/361
LCM = 23450427
Thus, we can understand that the LCM of 247,959,209,171 is 23450427.
