Given numbers are 788,781,836,791,766
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 788,781,836,791,766 is 3542469418796.
Find LCM of 788,781,836,791,766 with Prime Factorization
| 2 | 788, 781, 836, 791, 766 |
| 2 | 394, 781, 418, 791, 383 |
| 11 | 197, 781, 209, 791, 383 |
| 197, 71, 19, 791, 383 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 197 x 71 x 19 x 791 x 383 = 3542469418796
Therefore, the lowest common multiple of 788,781,836,791,766 is 3542469418796.
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.
788 x 781 x 836 x 791 x 766 = 311737308854048
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.
788 : 1, 2, 4, 197, 394, 788
781 : 1, 11, 71, 781
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
791 : 1, 7, 113, 791
766 : 1, 2, 383, 766
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 788,781,836,791,766, is 1.
Now, the common factors can be found like this.
788:2x 2x 197
781:11x 71
836:2x 2x 11x 19
791:7x 113
766:2x 383
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 11 = 88
Therefore, the value for common factors is 88.
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 = 311737308854048/(1x88)
LCM = 311737308854048/88
LCM = 3542469418796
Thus, we can understand that the LCM of 788,781,836,791,766 is 3542469418796.
