Given numbers are 721, 221, 187, 365
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(721, 221) = 159341
GCD(721, 221) = ( 721 x 221 ) / 159341
= 721 / 221
= 721
Step2:
LCM(1, 187) = 187
GCD(1, 187) = ( 1 x 187 ) / 187
= 1 / 187
= 1
Step3:
LCM(1, 365) = 365
GCD(1, 365) = ( 1 x 365 ) / 365
= 1 / 365
= 1
So, Greatest Common Divisor of 721, 221, 187, 365 is 1
