Given numbers are 105, 148, 913, 309
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(105, 148) = 15540
GCD(105, 148) = ( 105 x 148 ) / 15540
= 105 / 148
= 105
Step2:
LCM(1, 913) = 913
GCD(1, 913) = ( 1 x 913 ) / 913
= 1 / 913
= 1
Step3:
LCM(1, 309) = 309
GCD(1, 309) = ( 1 x 309 ) / 309
= 1 / 309
= 1
So, Greatest Common Divisor of 105, 148, 913, 309 is 1
