GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(305, 695) = 42395
GCD(305, 695) = ( 305 x 695 ) / 42395
= 305 / 695
= 305
Step2:
LCM(5, 942) = 4710
GCD(5, 942) = ( 5 x 942 ) / 4710
= 5 / 942
= 5
Step3:
LCM(1, 378) = 378
GCD(1, 378) = ( 1 x 378 ) / 378
= 1 / 378
= 1
So, Greatest Common Divisor of 305, 695, 942, 378 is 1
