Given numbers are 640, 676, 809, 871

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

Apply this formula for all numbers.

Step1:

LCM(640, 676) = 108160

GCD(640, 676) = ( 640 x 676 ) / 108160

= 640 / 676

= 640

Step2:

LCM(4, 809) = 3236

GCD(4, 809) = ( 4 x 809 ) / 3236

= 4 / 809

= 4

Step3:

LCM(1, 871) = 871

GCD(1, 871) = ( 1 x 871 ) / 871

= 1 / 871

= 1

So, Greatest Common Divisor of 640, 676, 809, 871 is 1
