GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(732, 212) = 38796
GCD(732, 212) = ( 732 x 212 ) / 38796
= 732 / 212
= 732
Step2:
LCM(4, 981) = 3924
GCD(4, 981) = ( 4 x 981 ) / 3924
= 4 / 981
= 4
Step3:
LCM(1, 648) = 648
GCD(1, 648) = ( 1 x 648 ) / 648
= 1 / 648
= 1
So, Greatest Common Divisor of 732, 212, 981, 648 is 1
