Given numbers are 189,813,551,560
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 189,813,551,560 is 2257733520.
Find LCM of 189,813,551,560 with Prime Factorization
| 3 | 189, 813, 551, 560 |
| 7 | 63, 271, 551, 560 |
| 9, 271, 551, 80 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 9 x 271 x 551 x 80 = 2257733520
Therefore, the lowest common multiple of 189,813,551,560 is 2257733520.
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.
189 x 813 x 551 x 560 = 47412403920
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.
189 : 1, 3, 7, 9, 21, 27, 63, 189
813 : 1, 3, 271, 813
551 : 1, 19, 29, 551
560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 189,813,551,560, is 1.
Now, the common factors can be found like this.
189:3x 3x 3x 7
813:3x 271
551:19x 29
560:2x 2x 2x 2x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7 = 21
Therefore, the value for common factors is 21.
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 = 47412403920/(1x21)
LCM = 47412403920/21
LCM = 2257733520
Thus, we can understand that the LCM of 189,813,551,560 is 2257733520.
