Given numbers are 728, 257, 401, 244
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(728, 257) = 187096
GCD(728, 257) = ( 728 x 257 ) / 187096
= 728 / 257
= 728
Step2:
LCM(1, 401) = 401
GCD(1, 401) = ( 1 x 401 ) / 401
= 1 / 401
= 1
Step3:
LCM(1, 244) = 244
GCD(1, 244) = ( 1 x 244 ) / 244
= 1 / 244
= 1
So, Greatest Common Divisor of 728, 257, 401, 244 is 1
