The LCM of 160,670,871,728 is 975520.
Find LCM of 160,670,871,728 with Prime Factorization
| 2 | 160, 670, 871, 728 |
| 2 | 80, 335, 871, 364 |
| 2 | 40, 335, 871, 182 |
| 5 | 20, 335, 871, 91 |
| 13 | 4, 67, 871, 91 |
| 67 | 4, 67, 67, 7 |
| 4, 1, 1, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 13 x 67 x 4 x 1 x 1 x 7 = 975520
Therefore, the lowest common multiple of 160,670,871,728 is 975520.
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 670 x 871 x 728 = 67974233600
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
670 : 1, 2, 5, 10, 67, 134, 335, 670
871 : 1, 13, 67, 871
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 160,670,871,728, is 1.
Now, the common factors can be found like this.
160:2x 2x 2x 2x 2x 5
670:2x 5x 67
871:13x 67
728:2x 2x 2x 7x 13
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 5x 13x 67 = 69680
Therefore, the value for common factors is 69680.
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 = 67974233600/(1x69680)
LCM = 67974233600/69680
LCM = 975520
Thus, we can understand that the LCM of 160,670,871,728 is 975520.
