Given numbers are 817, 609, 215, 179

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

Apply this formula for all numbers.

Step1:

LCM(817, 609) = 497553

GCD(817, 609) = ( 817 x 609 ) / 497553

= 817 / 609

= 817

Step2:

LCM(1, 215) = 215

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

= 1 / 215

= 1

Step3:

LCM(1, 179) = 179

GCD(1, 179) = ( 1 x 179 ) / 179

= 1 / 179

= 1

So, Greatest Common Divisor of 817, 609, 215, 179 is 1
