Given numbers are 377, 109, 420
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(377, 109) = 41093
GCD(377, 109) = ( 377 x 109 ) / 41093
= 377 / 109
= 377
Step2:
LCM(1, 420) = 420
GCD(1, 420) = ( 1 x 420 ) / 420
= 1 / 420
= 1
So, Greatest Common Divisor of 377, 109, 420 is 1
