Given numbers are 664, 331, 873, 215
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(664, 331) = 219784
GCD(664, 331) = ( 664 x 331 ) / 219784
= 664 / 331
= 664
Step2:
LCM(1, 873) = 873
GCD(1, 873) = ( 1 x 873 ) / 873
= 1 / 873
= 1
Step3:
LCM(1, 215) = 215
GCD(1, 215) = ( 1 x 215 ) / 215
= 1 / 215
= 1
So, Greatest Common Divisor of 664, 331, 873, 215 is 1
