Given numbers are 129, 206, 909, 174
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(129, 206) = 26574
GCD(129, 206) = ( 129 x 206 ) / 26574
= 129 / 206
= 129
Step2:
LCM(1, 909) = 909
GCD(1, 909) = ( 1 x 909 ) / 909
= 1 / 909
= 1
Step3:
LCM(1, 174) = 174
GCD(1, 174) = ( 1 x 174 ) / 174
= 1 / 174
= 1
So, Greatest Common Divisor of 129, 206, 909, 174 is 1
