Given numbers are 615, 457, 788, 441

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

Apply this formula for all numbers.

Step1:

LCM(615, 457) = 281055

GCD(615, 457) = ( 615 x 457 ) / 281055

= 615 / 457

= 615

Step2:

LCM(1, 788) = 788

GCD(1, 788) = ( 1 x 788 ) / 788

= 1 / 788

= 1

Step3:

LCM(1, 441) = 441

GCD(1, 441) = ( 1 x 441 ) / 441

= 1 / 441

= 1

So, Greatest Common Divisor of 615, 457, 788, 441 is 1
