Given numbers are 902, 817, 21, 923

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

Apply this formula for all numbers.

Step1:

LCM(902, 817) = 736934

GCD(902, 817) = ( 902 x 817 ) / 736934

= 902 / 817

= 902

Step2:

LCM(1, 21) = 21

GCD(1, 21) = ( 1 x 21 ) / 21

= 1 / 21

= 1

Step3:

LCM(1, 923) = 923

GCD(1, 923) = ( 1 x 923 ) / 923

= 1 / 923

= 1

So, Greatest Common Divisor of 902, 817, 21, 923 is 1
