Given numbers are 378, 351, 161
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(378, 351) = 4914
GCD(378, 351) = ( 378 x 351 ) / 4914
= 378 / 351
= 378
Step2:
LCM(27, 161) = 4347
GCD(27, 161) = ( 27 x 161 ) / 4347
= 27 / 161
= 27
So, Greatest Common Divisor of 378, 351, 161 is 1
