Given numbers are 160,398,720,616
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 160,398,720,616 is 22065120.
Find LCM of 160,398,720,616 with Prime Factorization
| 2 | 160, 398, 720, 616 |
| 2 | 80, 199, 360, 308 |
| 2 | 40, 199, 180, 154 |
| 2 | 20, 199, 90, 77 |
| 5 | 10, 199, 45, 77 |
| 2, 199, 9, 77 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 5 x 2 x 199 x 9 x 77 = 22065120
Therefore, the lowest common multiple of 160,398,720,616 is 22065120.
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.
160 x 398 x 720 x 616 = 28243353600
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.
160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160
398 : 1, 2, 199, 398
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 160,398,720,616, is 2.
Now, the common factors can be found like this.
160:2x 2x 2x 2x 2x 5
398:2x 199
720:2x 2x 2x 2x 3x 3x 5
616:2x 2x 2x 7x 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 2x 2x 2x 2x 2x 5 = 640
Therefore, the value for common factors is 640.
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 = 28243353600/(2x640)
LCM = 28243353600/1280
LCM = 22065120
Thus, we can understand that the LCM of 160,398,720,616 is 22065120.
