GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(398, 920) = 183080
GCD(398, 920) = ( 398 x 920 ) / 183080
= 398 / 920
= 398
Step2:
LCM(2, 864) = 864
GCD(2, 864) = ( 2 x 864 ) / 864
= 2 / 864
= 2
Step3:
LCM(2, 940) = 940
GCD(2, 940) = ( 2 x 940 ) / 940
= 2 / 940
= 2
So, Greatest Common Divisor of 398, 920, 864, 940 is 2
