Given numbers are 821, 210, 185, 481
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(821, 210) = 172410
GCD(821, 210) = ( 821 x 210 ) / 172410
= 821 / 210
= 821
Step2:
LCM(1, 185) = 185
GCD(1, 185) = ( 1 x 185 ) / 185
= 1 / 185
= 1
Step3:
LCM(1, 481) = 481
GCD(1, 481) = ( 1 x 481 ) / 481
= 1 / 481
= 1
So, Greatest Common Divisor of 821, 210, 185, 481 is 1
