Given numbers are 309, 626, 689, 593
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(309, 626) = 193434
GCD(309, 626) = ( 309 x 626 ) / 193434
= 309 / 626
= 309
Step2:
LCM(1, 689) = 689
GCD(1, 689) = ( 1 x 689 ) / 689
= 1 / 689
= 1
Step3:
LCM(1, 593) = 593
GCD(1, 593) = ( 1 x 593 ) / 593
= 1 / 593
= 1
So, Greatest Common Divisor of 309, 626, 689, 593 is 1
