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
