Given numbers are 228, 153, 669, 691
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(228, 153) = 11628
GCD(228, 153) = ( 228 x 153 ) / 11628
= 228 / 153
= 228
Step2:
LCM(3, 669) = 669
GCD(3, 669) = ( 3 x 669 ) / 669
= 3 / 669
= 3
Step3:
LCM(3, 691) = 2073
GCD(3, 691) = ( 3 x 691 ) / 2073
= 3 / 691
= 3
So, Greatest Common Divisor of 228, 153, 669, 691 is 1
