GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(217, 981) = 212877
GCD(217, 981) = ( 217 x 981 ) / 212877
= 217 / 981
= 217
Step2:
LCM(1, 405) = 405
GCD(1, 405) = ( 1 x 405 ) / 405
= 1 / 405
= 1
Step3:
LCM(1, 887) = 887
GCD(1, 887) = ( 1 x 887 ) / 887
= 1 / 887
= 1
So, Greatest Common Divisor of 217, 981, 405, 887 is 1
