Given numbers are 991, 212, 615, 591

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(991, 212) = 210092

GCD(991, 212) = ( 991 x 212 ) / 210092

= 991 / 212

= 991

Step2:

LCM(1, 615) = 615

GCD(1, 615) = ( 1 x 615 ) / 615

= 1 / 615

= 1

Step3:

LCM(1, 591) = 591

GCD(1, 591) = ( 1 x 591 ) / 591

= 1 / 591

= 1

So, Greatest Common Divisor of 991, 212, 615, 591 is 1
