Given numbers are 137, 193, 881, 420

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

Apply this formula for all numbers.

Step1:

LCM(137, 193) = 26441

GCD(137, 193) = ( 137 x 193 ) / 26441

= 137 / 193

= 137

Step2:

LCM(1, 881) = 881

GCD(1, 881) = ( 1 x 881 ) / 881

= 1 / 881

= 1

Step3:

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

= 1 / 420

= 1

So, Greatest Common Divisor of 137, 193, 881, 420 is 1
