Given numbers are 687, 778, 991, 295

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

Apply this formula for all numbers.

Step1:

LCM(687, 778) = 534486

GCD(687, 778) = ( 687 x 778 ) / 534486

= 687 / 778

= 687

Step2:

LCM(1, 991) = 991

GCD(1, 991) = ( 1 x 991 ) / 991

= 1 / 991

= 1

Step3:

LCM(1, 295) = 295

GCD(1, 295) = ( 1 x 295 ) / 295

= 1 / 295

= 1

So, Greatest Common Divisor of 687, 778, 991, 295 is 1
