Given numbers are 997, 471, 473, 220
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(997, 471) = 469587
GCD(997, 471) = ( 997 x 471 ) / 469587
= 997 / 471
= 997
Step2:
LCM(1, 473) = 473
GCD(1, 473) = ( 1 x 473 ) / 473
= 1 / 473
= 1
Step3:
LCM(1, 220) = 220
GCD(1, 220) = ( 1 x 220 ) / 220
= 1 / 220
= 1
So, Greatest Common Divisor of 997, 471, 473, 220 is 1
