Given numbers are 401, 640, 266, 540
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(401, 640) = 256640
GCD(401, 640) = ( 401 x 640 ) / 256640
= 401 / 640
= 401
Step2:
LCM(1, 266) = 266
GCD(1, 266) = ( 1 x 266 ) / 266
= 1 / 266
= 1
Step3:
LCM(1, 540) = 540
GCD(1, 540) = ( 1 x 540 ) / 540
= 1 / 540
= 1
So, Greatest Common Divisor of 401, 640, 266, 540 is 1
