Given numbers are 438,209,530,209,880
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 438,209,530,209,880 is 194069040.
Find LCM of 438,209,530,209,880 with Prime Factorization
| 2 | 438, 209, 530, 209, 880 |
| 5 | 219, 209, 265, 209, 440 |
| 11 | 219, 209, 53, 209, 88 |
| 19 | 219, 19, 53, 19, 8 |
| 219, 1, 53, 1, 8 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 19 x 219 x 1 x 53 x 1 x 8 = 194069040
Therefore, the lowest common multiple of 438,209,530,209,880 is 194069040.
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.
438 x 209 x 530 x 209 x 880 = 8923294459200
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.
438 : 1, 2, 3, 6, 73, 146, 219, 438
209 : 1, 11, 19, 209
530 : 1, 2, 5, 10, 53, 106, 265, 530
209 : 1, 11, 19, 209
880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 438,209,530,209,880, is 1.
Now, the common factors can be found like this.
438:2x 3x 73
209:11x 19
530:2x 5x 53
209:11x 19
880:2x 2x 2x 2x 5x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 5x 11x 11x 19 = 45980
Therefore, the value for common factors is 45980.
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 = 8923294459200/(1x45980)
LCM = 8923294459200/45980
LCM = 194069040
Thus, we can understand that the LCM of 438,209,530,209,880 is 194069040.
