Given numbers are 831,747,234,991,810
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 831,747,234,991,810 is 239916372930.
Find LCM of 831,747,234,991,810 with Prime Factorization
| 2 | 831, 747, 234, 991, 810 |
| 3 | 831, 747, 117, 991, 405 |
| 3 | 277, 249, 39, 991, 135 |
| 277, 83, 13, 991, 45 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 277 x 83 x 13 x 991 x 45 = 239916372930
Therefore, the lowest common multiple of 831,747,234,991,810 is 239916372930.
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 747 x 234 x 991 x 810 = 116599357243980
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
747 : 1, 3, 9, 83, 249, 747
234 : 1, 2, 3, 6, 9, 13, 18, 26, 39, 78, 117, 234
991 : 1, 991
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 831,747,234,991,810, is 1.
Now, the common factors can be found like this.
831:3x 277
747:3x 3x 83
234:2x 3x 3x 13
991:991
810:2x 3x 3x 3x 3x 5
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 3x 3x 3 = 486
Therefore, the value for common factors is 486.
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 = 116599357243980/(1x486)
LCM = 116599357243980/486
LCM = 239916372930
Thus, we can understand that the LCM of 831,747,234,991,810 is 239916372930.
