Given numbers are 688, 561, 369, 880

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

Apply this formula for all numbers.

Step1:

LCM(688, 561) = 385968

GCD(688, 561) = ( 688 x 561 ) / 385968

= 688 / 561

= 688

Step2:

LCM(1, 369) = 369

GCD(1, 369) = ( 1 x 369 ) / 369

= 1 / 369

= 1

Step3:

LCM(1, 880) = 880

GCD(1, 880) = ( 1 x 880 ) / 880

= 1 / 880

= 1

So, Greatest Common Divisor of 688, 561, 369, 880 is 1
