Given numbers are 421, 147, 380

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(421, 147) = 61887

GCD(421, 147) = ( 421 x 147 ) / 61887

= 421 / 147

= 421

Step2:

LCM(1, 380) = 380

GCD(1, 380) = ( 1 x 380 ) / 380

= 1 / 380

= 1

So, Greatest Common Divisor of 421, 147, 380 is 1
