Given numbers are 654, 251, 391, 219

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

Apply this formula for all numbers.

Step1:

LCM(654, 251) = 164154

GCD(654, 251) = ( 654 x 251 ) / 164154

= 654 / 251

= 654

Step2:

LCM(1, 391) = 391

GCD(1, 391) = ( 1 x 391 ) / 391

= 1 / 391

= 1

Step3:

LCM(1, 219) = 219

GCD(1, 219) = ( 1 x 219 ) / 219

= 1 / 219

= 1

So, Greatest Common Divisor of 654, 251, 391, 219 is 1
