Given numbers are 603, 687, 631, 805
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(603, 687) = 138087
GCD(603, 687) = ( 603 x 687 ) / 138087
= 603 / 687
= 603
Step2:
LCM(3, 631) = 1893
GCD(3, 631) = ( 3 x 631 ) / 1893
= 3 / 631
= 3
Step3:
LCM(1, 805) = 805
GCD(1, 805) = ( 1 x 805 ) / 805
= 1 / 805
= 1
So, Greatest Common Divisor of 603, 687, 631, 805 is 1
