Given numbers are 809, 455, 151, 649
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(809, 455) = 368095
GCD(809, 455) = ( 809 x 455 ) / 368095
= 809 / 455
= 809
Step2:
LCM(1, 151) = 151
GCD(1, 151) = ( 1 x 151 ) / 151
= 1 / 151
= 1
Step3:
LCM(1, 649) = 649
GCD(1, 649) = ( 1 x 649 ) / 649
= 1 / 649
= 1
So, Greatest Common Divisor of 809, 455, 151, 649 is 1
