Given numbers are 817, 208, 560, 166
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(817, 208) = 169936
GCD(817, 208) = ( 817 x 208 ) / 169936
= 817 / 208
= 817
Step2:
LCM(1, 560) = 560
GCD(1, 560) = ( 1 x 560 ) / 560
= 1 / 560
= 1
Step3:
LCM(1, 166) = 166
GCD(1, 166) = ( 1 x 166 ) / 166
= 1 / 166
= 1
So, Greatest Common Divisor of 817, 208, 560, 166 is 1
