Given numbers are 165, 721, 338, 776
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(165, 721) = 118965
GCD(165, 721) = ( 165 x 721 ) / 118965
= 165 / 721
= 165
Step2:
LCM(1, 338) = 338
GCD(1, 338) = ( 1 x 338 ) / 338
= 1 / 338
= 1
Step3:
LCM(1, 776) = 776
GCD(1, 776) = ( 1 x 776 ) / 776
= 1 / 776
= 1
So, Greatest Common Divisor of 165, 721, 338, 776 is 1
