Given numbers are 834,217,847,31
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 834,217,847,31 is 21898338.
Find LCM of 834,217,847,31 with Prime Factorization
| 7 | 834, 217, 847, 31 |
| 31 | 834, 31, 121, 31 |
| 834, 1, 121, 1 |
Multiply the prime numbers at the bottom and the left side.
7 x 31 x 834 x 1 x 121 x 1 = 21898338
Therefore, the lowest common multiple of 834,217,847,31 is 21898338.
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.
834 x 217 x 847 x 31 = 4751939346
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.
834 : 1, 2, 3, 6, 139, 278, 417, 834
217 : 1, 7, 31, 217
847 : 1, 7, 11, 77, 121, 847
31 : 1, 31
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 834,217,847,31, is 1.
Now, the common factors can be found like this.
834:2x 3x 139
217:7x 31
847:7x 11x 11
31:31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 31 = 217
Therefore, the value for common factors is 217.
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 = 4751939346/(1x217)
LCM = 4751939346/217
LCM = 21898338
Thus, we can understand that the LCM of 834,217,847,31 is 21898338.
