Given numbers are 691,699,867,345,217
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 691,699,867,345,217 is 3483458492955.
Find LCM of 691,699,867,345,217 with Prime Factorization
3 | 691, 699, 867, 345, 217 |
691, 233, 289, 115, 217 |
Multiply the prime numbers at the bottom and the left side.
3 x 691 x 233 x 289 x 115 x 217 = 3483458492955
Therefore, the lowest common multiple of 691,699,867,345,217 is 3483458492955.
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.
691 x 699 x 867 x 345 x 217 = 31351126436595
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.
691 : 1, 691
699 : 1, 3, 233, 699
867 : 1, 3, 17, 51, 289, 867
345 : 1, 3, 5, 15, 23, 69, 115, 345
217 : 1, 7, 31, 217
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 691,699,867,345,217, is 1.
Now, the common factors can be found like this.
691:691
699:3x 233
867:3x 17x 17
345:3x 5x 23
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.
3x 3 = 9
Therefore, the value for common factors is 9.
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 = 31351126436595/(1x9)
LCM = 31351126436595/9
LCM = 3483458492955
Thus, we can understand that the LCM of 691,699,867,345,217 is 3483458492955.
