Given numbers are 309, 261, 371, 159
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(309, 261) = 26883
GCD(309, 261) = ( 309 x 261 ) / 26883
= 309 / 261
= 309
Step2:
LCM(3, 371) = 1113
GCD(3, 371) = ( 3 x 371 ) / 1113
= 3 / 371
= 3
Step3:
LCM(1, 159) = 159
GCD(1, 159) = ( 1 x 159 ) / 159
= 1 / 159
= 1
So, Greatest Common Divisor of 309, 261, 371, 159 is 1
