Given numbers are 609, 390, 873, 971

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

Apply this formula for all numbers.

Step1:

LCM(609, 390) = 79170

GCD(609, 390) = ( 609 x 390 ) / 79170

= 609 / 390

= 609

Step2:

LCM(3, 873) = 873

GCD(3, 873) = ( 3 x 873 ) / 873

= 3 / 873

= 3

Step3:

LCM(3, 971) = 2913

GCD(3, 971) = ( 3 x 971 ) / 2913

= 3 / 971

= 3

So, Greatest Common Divisor of 609, 390, 873, 971 is 1
