Given numbers are 665, 153, 186, 208
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(665, 153) = 101745
GCD(665, 153) = ( 665 x 153 ) / 101745
= 665 / 153
= 665
Step2:
LCM(1, 186) = 186
GCD(1, 186) = ( 1 x 186 ) / 186
= 1 / 186
= 1
Step3:
LCM(1, 208) = 208
GCD(1, 208) = ( 1 x 208 ) / 208
= 1 / 208
= 1
So, Greatest Common Divisor of 665, 153, 186, 208 is 1
