Given numbers are 324,611,669,987
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 324,611,669,987 is 309021804.
Find LCM of 324,611,669,987 with Prime Factorization
| 3 | 324, 611, 669, 987 |
| 47 | 108, 611, 223, 329 |
| 108, 13, 223, 7 |
Multiply the prime numbers at the bottom and the left side.
3 x 47 x 108 x 13 x 223 x 7 = 309021804
Therefore, the lowest common multiple of 324,611,669,987 is 309021804.
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 611 x 669 x 987 = 130716223092
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
611 : 1, 13, 47, 611
669 : 1, 3, 223, 669
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 324,611,669,987, is 1.
Now, the common factors can be found like this.
324:2x 2x 3x 3x 3x 3
611:13x 47
669:3x 223
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.
3x 3x 47 = 423
Therefore, the value for common factors is 423.
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 = 130716223092/(1x423)
LCM = 130716223092/423
LCM = 309021804
Thus, we can understand that the LCM of 324,611,669,987 is 309021804.
