Given numbers are 903, 645, 991, 610

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

Apply this formula for all numbers.

Step1:

LCM(903, 645) = 4515

GCD(903, 645) = ( 903 x 645 ) / 4515

= 903 / 645

= 903

Step2:

LCM(129, 991) = 127839

GCD(129, 991) = ( 129 x 991 ) / 127839

= 129 / 991

= 129

Step3:

LCM(1, 610) = 610

GCD(1, 610) = ( 1 x 610 ) / 610

= 1 / 610

= 1

So, Greatest Common Divisor of 903, 645, 991, 610 is 1
