Given numbers are 261, 991, 640, 236

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(261, 991) = 258651

GCD(261, 991) = ( 261 x 991 ) / 258651

= 261 / 991

= 261

Step2:

LCM(1, 640) = 640

GCD(1, 640) = ( 1 x 640 ) / 640

= 1 / 640

= 1

Step3:

LCM(1, 236) = 236

GCD(1, 236) = ( 1 x 236 ) / 236

= 1 / 236

= 1

So, Greatest Common Divisor of 261, 991, 640, 236 is 1
