GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(177, 558) = 32922
GCD(177, 558) = ( 177 x 558 ) / 32922
= 177 / 558
= 177
Step2:
LCM(3, 298) = 894
GCD(3, 298) = ( 3 x 298 ) / 894
= 3 / 298
= 3
Step3:
LCM(1, 428) = 428
GCD(1, 428) = ( 1 x 428 ) / 428
= 1 / 428
= 1
So, Greatest Common Divisor of 177, 558, 298, 428 is 1
