GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(309, 813) = 83739
GCD(309, 813) = ( 309 x 813 ) / 83739
= 309 / 813
= 309
Step2:
LCM(3, 625) = 1875
GCD(3, 625) = ( 3 x 625 ) / 1875
= 3 / 625
= 3
Step3:
LCM(1, 457) = 457
GCD(1, 457) = ( 1 x 457 ) / 457
= 1 / 457
= 1
So, Greatest Common Divisor of 309, 813, 625, 457 is 1
