Given numbers are 308,681,227,991
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 308,681,227,991 is 207860268.
Find LCM of 308,681,227,991 with Prime Factorization
| 227 | 308, 681, 227, 991 |
| 308, 3, 1, 991 |
Multiply the prime numbers at the bottom and the left side.
227 x 308 x 3 x 1 x 991 = 207860268
Therefore, the lowest common multiple of 308,681,227,991 is 207860268.
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.
308 x 681 x 227 x 991 = 47184280836
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.
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
681 : 1, 3, 227, 681
227 : 1, 227
991 : 1, 991
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 308,681,227,991, is 1.
Now, the common factors can be found like this.
308:2x 2x 7x 11
681:3x 227
227:227
991:991
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
227 = 227
Therefore, the value for common factors is 227.
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 = 47184280836/(1x227)
LCM = 47184280836/227
LCM = 207860268
Thus, we can understand that the LCM of 308,681,227,991 is 207860268.
