Given numbers are 206, 845, 871, 615
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(206, 845) = 174070
GCD(206, 845) = ( 206 x 845 ) / 174070
= 206 / 845
= 206
Step2:
LCM(1, 871) = 871
GCD(1, 871) = ( 1 x 871 ) / 871
= 1 / 871
= 1
Step3:
LCM(1, 615) = 615
GCD(1, 615) = ( 1 x 615 ) / 615
= 1 / 615
= 1
So, Greatest Common Divisor of 206, 845, 871, 615 is 1
