Given numbers are 688, 896, 553, 991

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

Apply this formula for all numbers.

Step1:

LCM(688, 896) = 38528

GCD(688, 896) = ( 688 x 896 ) / 38528

= 688 / 896

= 688

Step2:

LCM(16, 553) = 8848

GCD(16, 553) = ( 16 x 553 ) / 8848

= 16 / 553

= 16

Step3:

LCM(1, 991) = 991

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

= 1 / 991

= 1

So, Greatest Common Divisor of 688, 896, 553, 991 is 1
