Given numbers are 688, 822, 53, 256

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

Apply this formula for all numbers.

Step1:

LCM(688, 822) = 282768

GCD(688, 822) = ( 688 x 822 ) / 282768

= 688 / 822

= 688

Step2:

LCM(2, 53) = 106

GCD(2, 53) = ( 2 x 53 ) / 106

= 2 / 53

= 2

Step3:

LCM(1, 256) = 256

GCD(1, 256) = ( 1 x 256 ) / 256

= 1 / 256

= 1

So, Greatest Common Divisor of 688, 822, 53, 256 is 1
