Given numbers are 225, 865, 721, 274
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(225, 865) = 38925
GCD(225, 865) = ( 225 x 865 ) / 38925
= 225 / 865
= 225
Step2:
LCM(5, 721) = 3605
GCD(5, 721) = ( 5 x 721 ) / 3605
= 5 / 721
= 5
Step3:
LCM(1, 274) = 274
GCD(1, 274) = ( 1 x 274 ) / 274
= 1 / 274
= 1
So, Greatest Common Divisor of 225, 865, 721, 274 is 1
