Given numbers are 377, 189, 120, 477
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(377, 189) = 71253
GCD(377, 189) = ( 377 x 189 ) / 71253
= 377 / 189
= 377
Step2:
LCM(1, 120) = 120
GCD(1, 120) = ( 1 x 120 ) / 120
= 1 / 120
= 1
Step3:
LCM(1, 477) = 477
GCD(1, 477) = ( 1 x 477 ) / 477
= 1 / 477
= 1
So, Greatest Common Divisor of 377, 189, 120, 477 is 1
