GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(688, 944) = 40592
GCD(688, 944) = ( 688 x 944 ) / 40592
= 688 / 944
= 688
Step2:
LCM(16, 905) = 14480
GCD(16, 905) = ( 16 x 905 ) / 14480
= 16 / 905
= 16
Step3:
LCM(1, 940) = 940
GCD(1, 940) = ( 1 x 940 ) / 940
= 1 / 940
= 1
So, Greatest Common Divisor of 688, 944, 905, 940 is 1
