Given numbers are 613,560,685,280
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 613,560,685,280 is 47029360.
Find LCM of 613,560,685,280 with Prime Factorization
| 2 | 613, 560, 685, 280 |
| 2 | 613, 280, 685, 140 |
| 2 | 613, 70, 685, 140 |
| 5 | 613, 35, 685, 70 |
| 7 | 613, 7, 137, 14 |
| 613, 1, 137, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 7 x 613 x 1 x 137 x 2 = 47029360
Therefore, the lowest common multiple of 613,560,685,280 is 47029360.
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.
613 x 560 x 685 x 280 = 65841104000
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.
613 : 1, 613
560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560
685 : 1, 5, 137, 685
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 613,560,685,280, is 1.
Now, the common factors can be found like this.
613:613
560:2x 2x 2x 2x 5x 7
685:5x 137
280:2x 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.
2x 2x 2x 5x 5x 7 = 1400
Therefore, the value for common factors is 1400.
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 = 65841104000/(1x1400)
LCM = 65841104000/1400
LCM = 47029360
Thus, we can understand that the LCM of 613,560,685,280 is 47029360.
