Given numbers are 988, 429, 245, 980

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

Apply this formula for all numbers.

Step1:

LCM(988, 429) = 32604

GCD(988, 429) = ( 988 x 429 ) / 32604

= 988 / 429

= 988

Step2:

LCM(13, 245) = 3185

GCD(13, 245) = ( 13 x 245 ) / 3185

= 13 / 245

= 13

Step3:

LCM(1, 980) = 980

GCD(1, 980) = ( 1 x 980 ) / 980

= 1 / 980

= 1

So, Greatest Common Divisor of 988, 429, 245, 980 is 1
