GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(772, 788) = 152084
GCD(772, 788) = ( 772 x 788 ) / 152084
= 772 / 788
= 772
Step2:
LCM(4, 660) = 660
GCD(4, 660) = ( 4 x 660 ) / 660
= 4 / 660
= 4
Step3:
LCM(4, 988) = 988
GCD(4, 988) = ( 4 x 988 ) / 988
= 4 / 988
= 4
So, Greatest Common Divisor of 772, 788, 660, 988 is 4
