Given numbers are 397, 864, 149, 161
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(397, 864) = 343008
GCD(397, 864) = ( 397 x 864 ) / 343008
= 397 / 864
= 397
Step2:
LCM(1, 149) = 149
GCD(1, 149) = ( 1 x 149 ) / 149
= 1 / 149
= 1
Step3:
LCM(1, 161) = 161
GCD(1, 161) = ( 1 x 161 ) / 161
= 1 / 161
= 1
So, Greatest Common Divisor of 397, 864, 149, 161 is 1
