Given numbers are 309, 913, 657, 958
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(309, 913) = 282117
GCD(309, 913) = ( 309 x 913 ) / 282117
= 309 / 913
= 309
Step2:
LCM(1, 657) = 657
GCD(1, 657) = ( 1 x 657 ) / 657
= 1 / 657
= 1
Step3:
LCM(1, 958) = 958
GCD(1, 958) = ( 1 x 958 ) / 958
= 1 / 958
= 1
So, Greatest Common Divisor of 309, 913, 657, 958 is 1
