Given numbers are 687, 208, 770, 266
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(687, 208) = 142896
GCD(687, 208) = ( 687 x 208 ) / 142896
= 687 / 208
= 687
Step2:
LCM(1, 770) = 770
GCD(1, 770) = ( 1 x 770 ) / 770
= 1 / 770
= 1
Step3:
LCM(1, 266) = 266
GCD(1, 266) = ( 1 x 266 ) / 266
= 1 / 266
= 1
So, Greatest Common Divisor of 687, 208, 770, 266 is 1
