Given numbers are 331, 372, 785, 687
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(331, 372) = 123132
GCD(331, 372) = ( 331 x 372 ) / 123132
= 331 / 372
= 331
Step2:
LCM(1, 785) = 785
GCD(1, 785) = ( 1 x 785 ) / 785
= 1 / 785
= 1
Step3:
LCM(1, 687) = 687
GCD(1, 687) = ( 1 x 687 ) / 687
= 1 / 687
= 1
So, Greatest Common Divisor of 331, 372, 785, 687 is 1
