Given numbers are 938, 161, 225, 940
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(938, 161) = 21574
GCD(938, 161) = ( 938 x 161 ) / 21574
= 938 / 161
= 938
Step2:
LCM(7, 225) = 1575
GCD(7, 225) = ( 7 x 225 ) / 1575
= 7 / 225
= 7
Step3:
LCM(1, 940) = 940
GCD(1, 940) = ( 1 x 940 ) / 940
= 1 / 940
= 1
So, Greatest Common Divisor of 938, 161, 225, 940 is 1
