Given numbers are 665, 616, 497, 164
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(665, 616) = 58520
GCD(665, 616) = ( 665 x 616 ) / 58520
= 665 / 616
= 665
Step2:
LCM(7, 497) = 497
GCD(7, 497) = ( 7 x 497 ) / 497
= 7 / 497
= 7
Step3:
LCM(7, 164) = 1148
GCD(7, 164) = ( 7 x 164 ) / 1148
= 7 / 164
= 7
So, Greatest Common Divisor of 665, 616, 497, 164 is 1
