Given numbers are 209, 338, 988, 157

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

Apply this formula for all numbers.

Step1:

LCM(209, 338) = 70642

GCD(209, 338) = ( 209 x 338 ) / 70642

= 209 / 338

= 209

Step2:

LCM(1, 988) = 988

GCD(1, 988) = ( 1 x 988 ) / 988

= 1 / 988

= 1

Step3:

LCM(1, 157) = 157

GCD(1, 157) = ( 1 x 157 ) / 157

= 1 / 157

= 1

So, Greatest Common Divisor of 209, 338, 988, 157 is 1
