Given numbers are 997, 903, 816, 661

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

Apply this formula for all numbers.

Step1:

LCM(997, 903) = 900291

GCD(997, 903) = ( 997 x 903 ) / 900291

= 997 / 903

= 997

Step2:

LCM(1, 816) = 816

GCD(1, 816) = ( 1 x 816 ) / 816

= 1 / 816

= 1

Step3:

LCM(1, 661) = 661

GCD(1, 661) = ( 1 x 661 ) / 661

= 1 / 661

= 1

So, Greatest Common Divisor of 997, 903, 816, 661 is 1
