Given numbers are 458, 419, 618, 646
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(458, 419) = 191902
GCD(458, 419) = ( 458 x 419 ) / 191902
= 458 / 419
= 458
Step2:
LCM(1, 618) = 618
GCD(1, 618) = ( 1 x 618 ) / 618
= 1 / 618
= 1
Step3:
LCM(1, 646) = 646
GCD(1, 646) = ( 1 x 646 ) / 646
= 1 / 646
= 1
So, Greatest Common Divisor of 458, 419, 618, 646 is 1
