Given numbers are 166, 409, 615, 191
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(166, 409) = 67894
GCD(166, 409) = ( 166 x 409 ) / 67894
= 166 / 409
= 166
Step2:
LCM(1, 615) = 615
GCD(1, 615) = ( 1 x 615 ) / 615
= 1 / 615
= 1
Step3:
LCM(1, 191) = 191
GCD(1, 191) = ( 1 x 191 ) / 191
= 1 / 191
= 1
So, Greatest Common Divisor of 166, 409, 615, 191 is 1
