Given numbers are 688, 243, 429, 554

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

Apply this formula for all numbers.

Step1:

LCM(688, 243) = 167184

GCD(688, 243) = ( 688 x 243 ) / 167184

= 688 / 243

= 688

Step2:

LCM(1, 429) = 429

GCD(1, 429) = ( 1 x 429 ) / 429

= 1 / 429

= 1

Step3:

LCM(1, 554) = 554

GCD(1, 554) = ( 1 x 554 ) / 554

= 1 / 554

= 1

So, Greatest Common Divisor of 688, 243, 429, 554 is 1
