Given numbers are 509, 644, 80, 875

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

Apply this formula for all numbers.

Step1:

LCM(509, 644) = 327796

GCD(509, 644) = ( 509 x 644 ) / 327796

= 509 / 644

= 509

Step2:

LCM(1, 80) = 80

GCD(1, 80) = ( 1 x 80 ) / 80

= 1 / 80

= 1

Step3:

LCM(1, 875) = 875

GCD(1, 875) = ( 1 x 875 ) / 875

= 1 / 875

= 1

So, Greatest Common Divisor of 509, 644, 80, 875 is 1
