Given numbers are 831,706,781,390,525
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 831,706,781,390,525 is 1042409017650.
Find LCM of 831,706,781,390,525 with Prime Factorization
| 2 | 831, 706, 781, 390, 525 |
| 3 | 831, 353, 781, 195, 525 |
| 5 | 277, 353, 781, 65, 175 |
| 277, 353, 781, 13, 35 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 277 x 353 x 781 x 13 x 35 = 1042409017650
Therefore, the lowest common multiple of 831,706,781,390,525 is 1042409017650.
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.
831 x 706 x 781 x 390 x 525 = 93816811588500
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.
831 : 1, 3, 277, 831
706 : 1, 2, 353, 706
781 : 1, 11, 71, 781
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
525 : 1, 3, 5, 7, 15, 21, 25, 35, 75, 105, 175, 525
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 831,706,781,390,525, is 1.
Now, the common factors can be found like this.
831:3x 277
706:2x 353
781:11x 71
390:2x 3x 5x 13
525:3x 5x 5x 7
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 3x 5 = 90
Therefore, the value for common factors is 90.
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 = 93816811588500/(1x90)
LCM = 93816811588500/90
LCM = 1042409017650
Thus, we can understand that the LCM of 831,706,781,390,525 is 1042409017650.
