Given numbers are 161, 399, 392, 170
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(161, 399) = 9177
GCD(161, 399) = ( 161 x 399 ) / 9177
= 161 / 399
= 161
Step2:
LCM(7, 392) = 392
GCD(7, 392) = ( 7 x 392 ) / 392
= 7 / 392
= 7
Step3:
LCM(7, 170) = 1190
GCD(7, 170) = ( 7 x 170 ) / 1190
= 7 / 170
= 7
So, Greatest Common Divisor of 161, 399, 392, 170 is 1
