Given numbers are 133, 661, 305, 173
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(133, 661) = 87913
GCD(133, 661) = ( 133 x 661 ) / 87913
= 133 / 661
= 133
Step2:
LCM(1, 305) = 305
GCD(1, 305) = ( 1 x 305 ) / 305
= 1 / 305
= 1
Step3:
LCM(1, 173) = 173
GCD(1, 173) = ( 1 x 173 ) / 173
= 1 / 173
= 1
So, Greatest Common Divisor of 133, 661, 305, 173 is 1
