Given numbers are 987,308,253,317
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 987,308,253,317 is 316633548.
Find LCM of 987,308,253,317 with Prime Factorization
| 7 | 987, 308, 253, 317 |
| 11 | 141, 44, 253, 317 |
| 141, 4, 23, 317 |
Multiply the prime numbers at the bottom and the left side.
7 x 11 x 141 x 4 x 23 x 317 = 316633548
Therefore, the lowest common multiple of 987,308,253,317 is 316633548.
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.
987 x 308 x 253 x 317 = 24380783196
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.
987 : 1, 3, 7, 21, 47, 141, 329, 987
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
253 : 1, 11, 23, 253
317 : 1, 317
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 987,308,253,317, is 1.
Now, the common factors can be found like this.
987:3x 7x 47
308:2x 2x 7x 11
253:11x 23
317:317
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 11 = 77
Therefore, the value for common factors is 77.
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 = 24380783196/(1x77)
LCM = 24380783196/77
LCM = 316633548
Thus, we can understand that the LCM of 987,308,253,317 is 316633548.
