Given numbers are 247,209,685,168
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 247,209,685,168 is 312672360.
Find LCM of 247,209,685,168 with Prime Factorization
19 | 247, 209, 685, 168 |
13, 11, 685, 168 |
Multiply the prime numbers at the bottom and the left side.
19 x 13 x 11 x 685 x 168 = 312672360
Therefore, the lowest common multiple of 247,209,685,168 is 312672360.
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 209 x 685 x 168 = 5940774840
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
209 : 1, 11, 19, 209
685 : 1, 5, 137, 685
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,209,685,168, is 1.
Now, the common factors can be found like this.
247:13x 19
209:11x 19
685:5x 137
168:2x 2x 2x 3x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
19 = 19
Therefore, the value for common factors is 19.
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 = 5940774840/(1x19)
LCM = 5940774840/19
LCM = 312672360
Thus, we can understand that the LCM of 247,209,685,168 is 312672360.
