Given numbers are 791,108,791,318
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 791,108,791,318 is 4527684.
Find LCM of 791,108,791,318 with Prime Factorization
| 2 | 791, 108, 791, 318 |
| 3 | 791, 54, 791, 159 |
| 7 | 791, 18, 791, 53 |
| 113 | 113, 18, 113, 53 |
| 1, 18, 1, 53 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 113 x 1 x 18 x 1 x 53 = 4527684
Therefore, the lowest common multiple of 791,108,791,318 is 4527684.
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.
791 x 108 x 791 x 318 = 21488388264
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.
791 : 1, 7, 113, 791
108 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 108
791 : 1, 7, 113, 791
318 : 1, 2, 3, 6, 53, 106, 159, 318
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 791,108,791,318, is 1.
Now, the common factors can be found like this.
791:7x 113
108:2x 2x 3x 3x 3
791:7x 113
318:2x 3x 53
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 7x 113 = 4746
Therefore, the value for common factors is 4746.
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 = 21488388264/(1x4746)
LCM = 21488388264/4746
LCM = 4527684
Thus, we can understand that the LCM of 791,108,791,318 is 4527684.
