Given numbers are 816, 345, 245, 756
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(816, 345) = 93840
GCD(816, 345) = ( 816 x 345 ) / 93840
= 816 / 345
= 816
Step2:
LCM(3, 245) = 735
GCD(3, 245) = ( 3 x 245 ) / 735
= 3 / 245
= 3
Step3:
LCM(1, 756) = 756
GCD(1, 756) = ( 1 x 756 ) / 756
= 1 / 756
= 1
So, Greatest Common Divisor of 816, 345, 245, 756 is 1
