Given numbers are 719, 781, 279, 215

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

Apply this formula for all numbers.

Step1:

LCM(719, 781) = 561539

GCD(719, 781) = ( 719 x 781 ) / 561539

= 719 / 781

= 719

Step2:

LCM(1, 279) = 279

GCD(1, 279) = ( 1 x 279 ) / 279

= 1 / 279

= 1

Step3:

LCM(1, 215) = 215

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

= 1 / 215

= 1

So, Greatest Common Divisor of 719, 781, 279, 215 is 1
