Given numbers are 640, 768, 401, 231
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(640, 768) = 3840
GCD(640, 768) = ( 640 x 768 ) / 3840
= 640 / 768
= 640
Step2:
LCM(128, 401) = 51328
GCD(128, 401) = ( 128 x 401 ) / 51328
= 128 / 401
= 128
Step3:
LCM(1, 231) = 231
GCD(1, 231) = ( 1 x 231 ) / 231
= 1 / 231
= 1
So, Greatest Common Divisor of 640, 768, 401, 231 is 1
