Given numbers are 169, 286, 170, 399
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(169, 286) = 3718
GCD(169, 286) = ( 169 x 286 ) / 3718
= 169 / 286
= 169
Step2:
LCM(13, 170) = 2210
GCD(13, 170) = ( 13 x 170 ) / 2210
= 13 / 170
= 13
Step3:
LCM(1, 399) = 399
GCD(1, 399) = ( 1 x 399 ) / 399
= 1 / 399
= 1
So, Greatest Common Divisor of 169, 286, 170, 399 is 1
