Given numbers are 464, 644, 191, 497
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(464, 644) = 74704
GCD(464, 644) = ( 464 x 644 ) / 74704
= 464 / 644
= 464
Step2:
LCM(4, 191) = 764
GCD(4, 191) = ( 4 x 191 ) / 764
= 4 / 191
= 4
Step3:
LCM(1, 497) = 497
GCD(1, 497) = ( 1 x 497 ) / 497
= 1 / 497
= 1
So, Greatest Common Divisor of 464, 644, 191, 497 is 1
