Given numbers are 711,403,279,197
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 711,403,279,197 is 56447001.
Find LCM of 711,403,279,197 with Prime Factorization
| 3 | 711, 403, 279, 197 |
| 3 | 237, 403, 93, 197 |
| 31 | 79, 403, 31, 197 |
| 79, 13, 1, 197 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 31 x 79 x 13 x 1 x 197 = 56447001
Therefore, the lowest common multiple of 711,403,279,197 is 56447001.
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.
711 x 403 x 279 x 197 = 15748713279
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.
711 : 1, 3, 9, 79, 237, 711
403 : 1, 13, 31, 403
279 : 1, 3, 9, 31, 93, 279
197 : 1, 197
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 711,403,279,197, is 1.
Now, the common factors can be found like this.
711:3x 3x 79
403:13x 31
279:3x 3x 31
197:197
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 31 = 279
Therefore, the value for common factors is 279.
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 = 15748713279/(1x279)
LCM = 15748713279/279
LCM = 56447001
Thus, we can understand that the LCM of 711,403,279,197 is 56447001.
