Given numbers are 689, 354, 268, 230
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(689, 354) = 243906
GCD(689, 354) = ( 689 x 354 ) / 243906
= 689 / 354
= 689
Step2:
LCM(1, 268) = 268
GCD(1, 268) = ( 1 x 268 ) / 268
= 1 / 268
= 1
Step3:
LCM(1, 230) = 230
GCD(1, 230) = ( 1 x 230 ) / 230
= 1 / 230
= 1
So, Greatest Common Divisor of 689, 354, 268, 230 is 1
