GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(579, 772) = 2316
GCD(579, 772) = ( 579 x 772 ) / 2316
= 579 / 772
= 579
Step2:
LCM(193, 917) = 176981
GCD(193, 917) = ( 193 x 917 ) / 176981
= 193 / 917
= 193
Step3:
LCM(1, 690) = 690
GCD(1, 690) = ( 1 x 690 ) / 690
= 1 / 690
= 1
So, Greatest Common Divisor of 579, 772, 917, 690 is 1
