Given numbers are 167,831,785,978,380
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 167,831,785,978,380 is 1349548038660.
Find LCM of 167,831,785,978,380 with Prime Factorization
| 2 | 167, 831, 785, 978, 380 |
| 3 | 167, 831, 785, 489, 190 |
| 5 | 167, 277, 785, 163, 190 |
| 167, 277, 157, 163, 38 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 167 x 277 x 157 x 163 x 38 = 1349548038660
Therefore, the lowest common multiple of 167,831,785,978,380 is 1349548038660.
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.
167 x 831 x 785 x 978 x 380 = 40486441159800
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.
167 : 1, 167
831 : 1, 3, 277, 831
785 : 1, 5, 157, 785
978 : 1, 2, 3, 6, 163, 326, 489, 978
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 167,831,785,978,380, is 1.
Now, the common factors can be found like this.
167:167
831:3x 277
785:5x 157
978:2x 3x 163
380:2x 2x 5x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5 = 30
Therefore, the value for common factors is 30.
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 = 40486441159800/(1x30)
LCM = 40486441159800/30
LCM = 1349548038660
Thus, we can understand that the LCM of 167,831,785,978,380 is 1349548038660.
