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

Apply this formula for all numbers.

Step1:

LCM(253, 805) = 8855

GCD(253, 805) = ( 253 x 805 ) / 8855

= 253 / 805

= 253

Step2:

LCM(23, 598) = 598

GCD(23, 598) = ( 23 x 598 ) / 598

= 23 / 598

= 23

Step3:

LCM(23, 989) = 989

GCD(23, 989) = ( 23 x 989 ) / 989

= 23 / 989

= 23

So, Greatest Common Divisor of 253, 805, 598, 989 is 23
