Given numbers are 455, 307, 689, 241
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(455, 307) = 139685
GCD(455, 307) = ( 455 x 307 ) / 139685
= 455 / 307
= 455
Step2:
LCM(1, 689) = 689
GCD(1, 689) = ( 1 x 689 ) / 689
= 1 / 689
= 1
Step3:
LCM(1, 241) = 241
GCD(1, 241) = ( 1 x 241 ) / 241
= 1 / 241
= 1
So, Greatest Common Divisor of 455, 307, 689, 241 is 1
