Given numbers are 631, 409, 677, 196
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(631, 409) = 258079
GCD(631, 409) = ( 631 x 409 ) / 258079
= 631 / 409
= 631
Step2:
LCM(1, 677) = 677
GCD(1, 677) = ( 1 x 677 ) / 677
= 1 / 677
= 1
Step3:
LCM(1, 196) = 196
GCD(1, 196) = ( 1 x 196 ) / 196
= 1 / 196
= 1
So, Greatest Common Divisor of 631, 409, 677, 196 is 1
