GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(378, 196) = 5292
GCD(378, 196) = ( 378 x 196 ) / 5292
= 378 / 196
= 378
Step2:
LCM(14, 786) = 5502
GCD(14, 786) = ( 14 x 786 ) / 5502
= 14 / 786
= 14
Step3:
LCM(2, 485) = 970
GCD(2, 485) = ( 2 x 485 ) / 970
= 2 / 485
= 2
So, Greatest Common Divisor of 378, 196, 786, 485 is 1
