GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(161, 874) = 6118
GCD(161, 874) = ( 161 x 874 ) / 6118
= 161 / 874
= 161
Step2:
LCM(23, 391) = 391
GCD(23, 391) = ( 23 x 391 ) / 391
= 23 / 391
= 23
Step3:
LCM(23, 954) = 21942
GCD(23, 954) = ( 23 x 954 ) / 21942
= 23 / 954
= 23
So, Greatest Common Divisor of 161, 874, 391, 954 is 1
