GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(270, 999) = 9990
GCD(270, 999) = ( 270 x 999 ) / 9990
= 270 / 999
= 270
Step2:
LCM(27, 646) = 17442
GCD(27, 646) = ( 27 x 646 ) / 17442
= 27 / 646
= 27
Step3:
LCM(1, 161) = 161
GCD(1, 161) = ( 1 x 161 ) / 161
= 1 / 161
= 1
So, Greatest Common Divisor of 270, 999, 646, 161 is 1
