Given numbers are 419, 689, 265, 263

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

Apply this formula for all numbers.

Step1:

LCM(419, 689) = 288691

GCD(419, 689) = ( 419 x 689 ) / 288691

= 419 / 689

= 419

Step2:

LCM(1, 265) = 265

GCD(1, 265) = ( 1 x 265 ) / 265

= 1 / 265

= 1

Step3:

LCM(1, 263) = 263

GCD(1, 263) = ( 1 x 263 ) / 263

= 1 / 263

= 1

So, Greatest Common Divisor of 419, 689, 265, 263 is 1
