Given numbers are 687, 331, 313, 139
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(687, 331) = 227397
GCD(687, 331) = ( 687 x 331 ) / 227397
= 687 / 331
= 687
Step2:
LCM(1, 313) = 313
GCD(1, 313) = ( 1 x 313 ) / 313
= 1 / 313
= 1
Step3:
LCM(1, 139) = 139
GCD(1, 139) = ( 1 x 139 ) / 139
= 1 / 139
= 1
So, Greatest Common Divisor of 687, 331, 313, 139 is 1
