Given numbers are 247, 309, 173, 132
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(247, 309) = 76323
GCD(247, 309) = ( 247 x 309 ) / 76323
= 247 / 309
= 247
Step2:
LCM(1, 173) = 173
GCD(1, 173) = ( 1 x 173 ) / 173
= 1 / 173
= 1
Step3:
LCM(1, 132) = 132
GCD(1, 132) = ( 1 x 132 ) / 132
= 1 / 132
= 1
So, Greatest Common Divisor of 247, 309, 173, 132 is 1
