Given numbers are 455, 124, 773, 821
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(455, 124) = 56420
GCD(455, 124) = ( 455 x 124 ) / 56420
= 455 / 124
= 455
Step2:
LCM(1, 773) = 773
GCD(1, 773) = ( 1 x 773 ) / 773
= 1 / 773
= 1
Step3:
LCM(1, 821) = 821
GCD(1, 821) = ( 1 x 821 ) / 821
= 1 / 821
= 1
So, Greatest Common Divisor of 455, 124, 773, 821 is 1
