Given numbers are 615, 185, 389, 313
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(615, 185) = 22755
GCD(615, 185) = ( 615 x 185 ) / 22755
= 615 / 185
= 615
Step2:
LCM(5, 389) = 1945
GCD(5, 389) = ( 5 x 389 ) / 1945
= 5 / 389
= 5
Step3:
LCM(1, 313) = 313
GCD(1, 313) = ( 1 x 313 ) / 313
= 1 / 313
= 1
So, Greatest Common Divisor of 615, 185, 389, 313 is 1
