Given numbers are 831,520,394,763
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 831,520,394,763 is 64952389320.
Find LCM of 831,520,394,763 with Prime Factorization
2 | 831, 520, 394, 763 |
831, 260, 197, 763 |
Multiply the prime numbers at the bottom and the left side.
2 x 831 x 260 x 197 x 763 = 64952389320
Therefore, the lowest common multiple of 831,520,394,763 is 64952389320.
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 520 x 394 x 763 = 129904778640
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
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
394 : 1, 2, 197, 394
763 : 1, 7, 109, 763
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 831,520,394,763, is 1.
Now, the common factors can be found like this.
831:3x 277
520:2x 2x 2x 5x 13
394:2x 197
763:7x 109
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 129904778640/(1x2)
LCM = 129904778640/2
LCM = 64952389320
Thus, we can understand that the LCM of 831,520,394,763 is 64952389320.
