Given numbers are 699,665,247,217
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 699,665,247,217 is 187328505.
Find LCM of 699,665,247,217 with Prime Factorization
| 7 | 699, 665, 247, 217 |
| 19 | 699, 95, 247, 31 |
| 699, 5, 13, 31 |
Multiply the prime numbers at the bottom and the left side.
7 x 19 x 699 x 5 x 13 x 31 = 187328505
Therefore, the lowest common multiple of 699,665,247,217 is 187328505.
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.
699 x 665 x 247 x 217 = 24914691165
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.
699 : 1, 3, 233, 699
665 : 1, 5, 7, 19, 35, 95, 133, 665
247 : 1, 13, 19, 247
217 : 1, 7, 31, 217
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 699,665,247,217, is 1.
Now, the common factors can be found like this.
699:3x 233
665:5x 7x 19
247:13x 19
217:7x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 19 = 133
Therefore, the value for common factors is 133.
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 = 24914691165/(1x133)
LCM = 24914691165/133
LCM = 187328505
Thus, we can understand that the LCM of 699,665,247,217 is 187328505.
