Given numbers are 401, 409, 874, 688
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(401, 409) = 164009
GCD(401, 409) = ( 401 x 409 ) / 164009
= 401 / 409
= 401
Step2:
LCM(1, 874) = 874
GCD(1, 874) = ( 1 x 874 ) / 874
= 1 / 874
= 1
Step3:
LCM(1, 688) = 688
GCD(1, 688) = ( 1 x 688 ) / 688
= 1 / 688
= 1
So, Greatest Common Divisor of 401, 409, 874, 688 is 1
