Given numbers are 324,786,722,731,987
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 324,786,722,731,987 is 3684993979716.
Find LCM of 324,786,722,731,987 with Prime Factorization
2 | 324, 786, 722, 731, 987 |
3 | 162, 393, 361, 731, 987 |
54, 131, 361, 731, 329 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 54 x 131 x 361 x 731 x 329 = 3684993979716
Therefore, the lowest common multiple of 324,786,722,731,987 is 3684993979716.
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.
324 x 786 x 722 x 731 x 987 = 132659783269776
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.
324 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 324
786 : 1, 2, 3, 6, 131, 262, 393, 786
722 : 1, 2, 19, 38, 361, 722
731 : 1, 17, 43, 731
987 : 1, 3, 7, 21, 47, 141, 329, 987
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 324,786,722,731,987, is 1.
Now, the common factors can be found like this.
324:2x 2x 3x 3x 3x 3
786:2x 3x 131
722:2x 19x 19
731:17x 43
987:3x 7x 47
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 3 = 36
Therefore, the value for common factors is 36.
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 = 132659783269776/(1x36)
LCM = 132659783269776/36
LCM = 3684993979716
Thus, we can understand that the LCM of 324,786,722,731,987 is 3684993979716.
