Given numbers are 988, 248, 161, 909

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

Apply this formula for all numbers.

Step1:

LCM(988, 248) = 61256

GCD(988, 248) = ( 988 x 248 ) / 61256

= 988 / 248

= 988

Step2:

LCM(4, 161) = 644

GCD(4, 161) = ( 4 x 161 ) / 644

= 4 / 161

= 4

Step3:

LCM(1, 909) = 909

GCD(1, 909) = ( 1 x 909 ) / 909

= 1 / 909

= 1

So, Greatest Common Divisor of 988, 248, 161, 909 is 1
