Given numbers are 603, 687, 139, 971
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, 139) = 417
GCD(3, 139) = ( 3 x 139 ) / 417
= 3 / 139
= 3
Step3:
LCM(1, 971) = 971
GCD(1, 971) = ( 1 x 971 ) / 971
= 1 / 971
= 1
So, Greatest Common Divisor of 603, 687, 139, 971 is 1
