GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(977, 988) = 965276
GCD(977, 988) = ( 977 x 988 ) / 965276
= 977 / 988
= 977
Step2:
LCM(1, 399) = 399
GCD(1, 399) = ( 1 x 399 ) / 399
= 1 / 399
= 1
Step3:
LCM(1, 249) = 249
GCD(1, 249) = ( 1 x 249 ) / 249
= 1 / 249
= 1
So, Greatest Common Divisor of 977, 988, 399, 249 is 1
