Given numbers are 438, 277, 258

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

Apply this formula for all numbers.

Step1:

LCM(438, 277) = 121326

GCD(438, 277) = ( 438 x 277 ) / 121326

= 438 / 277

= 438

Step2:

LCM(1, 258) = 258

GCD(1, 258) = ( 1 x 258 ) / 258

= 1 / 258

= 1

So, Greatest Common Divisor of 438, 277, 258 is 1
