Given numbers are 621, 255, 361, 223
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(621, 255) = 52785
GCD(621, 255) = ( 621 x 255 ) / 52785
= 621 / 255
= 621
Step2:
LCM(3, 361) = 1083
GCD(3, 361) = ( 3 x 361 ) / 1083
= 3 / 361
= 3
Step3:
LCM(1, 223) = 223
GCD(1, 223) = ( 1 x 223 ) / 223
= 1 / 223
= 1
So, Greatest Common Divisor of 621, 255, 361, 223 is 1
