Given numbers are 238, 772, 199, 215

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

Apply this formula for all numbers.

Step1:

LCM(238, 772) = 91868

GCD(238, 772) = ( 238 x 772 ) / 91868

= 238 / 772

= 238

Step2:

LCM(2, 199) = 398

GCD(2, 199) = ( 2 x 199 ) / 398

= 2 / 199

= 2

Step3:

LCM(1, 215) = 215

GCD(1, 215) = ( 1 x 215 ) / 215

= 1 / 215

= 1

So, Greatest Common Divisor of 238, 772, 199, 215 is 1
