Given numbers are 161, 437, 391, 845
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(161, 437) = 3059
GCD(161, 437) = ( 161 x 437 ) / 3059
= 161 / 437
= 161
Step2:
LCM(23, 391) = 391
GCD(23, 391) = ( 23 x 391 ) / 391
= 23 / 391
= 23
Step3:
LCM(23, 845) = 19435
GCD(23, 845) = ( 23 x 845 ) / 19435
= 23 / 845
= 23
So, Greatest Common Divisor of 161, 437, 391, 845 is 1
