Given numbers are 154, 189, 217, 284
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(154, 189) = 4158
GCD(154, 189) = ( 154 x 189 ) / 4158
= 154 / 189
= 154
Step2:
LCM(7, 217) = 217
GCD(7, 217) = ( 7 x 217 ) / 217
= 7 / 217
= 7
Step3:
LCM(7, 284) = 1988
GCD(7, 284) = ( 7 x 284 ) / 1988
= 7 / 284
= 7
So, Greatest Common Divisor of 154, 189, 217, 284 is 1
