Given numbers are 688, 855, 426, 233
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(688, 855) = 588240
GCD(688, 855) = ( 688 x 855 ) / 588240
= 688 / 855
= 688
Step2:
LCM(1, 426) = 426
GCD(1, 426) = ( 1 x 426 ) / 426
= 1 / 426
= 1
Step3:
LCM(1, 233) = 233
GCD(1, 233) = ( 1 x 233 ) / 233
= 1 / 233
= 1
So, Greatest Common Divisor of 688, 855, 426, 233 is 1
