Given numbers are 168, 690, 437, 712
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(168, 690) = 19320
GCD(168, 690) = ( 168 x 690 ) / 19320
= 168 / 690
= 168
Step2:
LCM(6, 437) = 2622
GCD(6, 437) = ( 6 x 437 ) / 2622
= 6 / 437
= 6
Step3:
LCM(1, 712) = 712
GCD(1, 712) = ( 1 x 712 ) / 712
= 1 / 712
= 1
So, Greatest Common Divisor of 168, 690, 437, 712 is 1
