Given numbers are 238, 786, 711, 217

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

Apply this formula for all numbers.

Step1:

LCM(238, 786) = 93534

GCD(238, 786) = ( 238 x 786 ) / 93534

= 238 / 786

= 238

Step2:

LCM(2, 711) = 1422

GCD(2, 711) = ( 2 x 711 ) / 1422

= 2 / 711

= 2

Step3:

LCM(1, 217) = 217

GCD(1, 217) = ( 1 x 217 ) / 217

= 1 / 217

= 1

So, Greatest Common Divisor of 238, 786, 711, 217 is 1
