The list of prime factors of all numbers are
Prime factors of 266 are 2 x 7 x 19
Prime factors of 780 are 2 x 2 x 3 x 5 x 13
Prime factors of 806 are 2 x 13 x 31
Prime factors of 345 are 3 x 5 x 23
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 266, 780, 806, 345
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(266, 780) = 103740
GCD(266, 780) = ( 266 x 780 ) / 103740
= 266 / 780
= 266
Step2:
LCM(2, 806) = 806
GCD(2, 806) = ( 2 x 806 ) / 806
= 2 / 806
= 2
Step3:
LCM(2, 345) = 690
GCD(2, 345) = ( 2 x 345 ) / 690
= 2 / 345
= 2
So, Greatest Common Divisor of 266, 780, 806, 345 is 1
