Given numbers are 218, 380, 778, 263

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

Apply this formula for all numbers.

Step1:

LCM(218, 380) = 41420

GCD(218, 380) = ( 218 x 380 ) / 41420

= 218 / 380

= 218

Step2:

LCM(2, 778) = 778

GCD(2, 778) = ( 2 x 778 ) / 778

= 2 / 778

= 2

Step3:

LCM(2, 263) = 526

GCD(2, 263) = ( 2 x 263 ) / 526

= 2 / 263

= 2

So, Greatest Common Divisor of 218, 380, 778, 263 is 1
