Given numbers are 831,763,312,436
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 831,763,312,436 is 65941512.
Find LCM of 831,763,312,436 with Prime Factorization
| 2 | 831, 763, 312, 436 |
| 2 | 831, 763, 156, 218 |
| 3 | 831, 763, 78, 109 |
| 109 | 277, 763, 26, 109 |
| 277, 7, 26, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 109 x 277 x 7 x 26 x 1 = 65941512
Therefore, the lowest common multiple of 831,763,312,436 is 65941512.
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 763 x 312 x 436 = 86251497696
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
763 : 1, 7, 109, 763
312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312
436 : 1, 2, 4, 109, 218, 436
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 831,763,312,436, is 1.
Now, the common factors can be found like this.
831:3x 277
763:7x 109
312:2x 2x 2x 3x 13
436:2x 2x 109
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 3x 109 = 1308
Therefore, the value for common factors is 1308.
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 = 86251497696/(1x1308)
LCM = 86251497696/1308
LCM = 65941512
Thus, we can understand that the LCM of 831,763,312,436 is 65941512.
