Given numbers are 173, 115, 649, 654
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(173, 115) = 19895
GCD(173, 115) = ( 173 x 115 ) / 19895
= 173 / 115
= 173
Step2:
LCM(1, 649) = 649
GCD(1, 649) = ( 1 x 649 ) / 649
= 1 / 649
= 1
Step3:
LCM(1, 654) = 654
GCD(1, 654) = ( 1 x 654 ) / 654
= 1 / 654
= 1
So, Greatest Common Divisor of 173, 115, 649, 654 is 1
