Given numbers are 687, 283, 917, 689
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(687, 283) = 194421
GCD(687, 283) = ( 687 x 283 ) / 194421
= 687 / 283
= 687
Step2:
LCM(1, 917) = 917
GCD(1, 917) = ( 1 x 917 ) / 917
= 1 / 917
= 1
Step3:
LCM(1, 689) = 689
GCD(1, 689) = ( 1 x 689 ) / 689
= 1 / 689
= 1
So, Greatest Common Divisor of 687, 283, 917, 689 is 1
