Given numbers are 971, 210, 665, 904
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(971, 210) = 203910
GCD(971, 210) = ( 971 x 210 ) / 203910
= 971 / 210
= 971
Step2:
LCM(1, 665) = 665
GCD(1, 665) = ( 1 x 665 ) / 665
= 1 / 665
= 1
Step3:
LCM(1, 904) = 904
GCD(1, 904) = ( 1 x 904 ) / 904
= 1 / 904
= 1
So, Greatest Common Divisor of 971, 210, 665, 904 is 1
