Given numbers are 137, 520, 209, 203

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

Apply this formula for all numbers.

Step1:

LCM(137, 520) = 71240

GCD(137, 520) = ( 137 x 520 ) / 71240

= 137 / 520

= 137

Step2:

LCM(1, 209) = 209

GCD(1, 209) = ( 1 x 209 ) / 209

= 1 / 209

= 1

Step3:

LCM(1, 203) = 203

GCD(1, 203) = ( 1 x 203 ) / 203

= 1 / 203

= 1

So, Greatest Common Divisor of 137, 520, 209, 203 is 1
