Given numbers are 685, 575, 805, 671

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

Apply this formula for all numbers.

Step1:

LCM(685, 575) = 78775

GCD(685, 575) = ( 685 x 575 ) / 78775

= 685 / 575

= 685

Step2:

LCM(5, 805) = 805

GCD(5, 805) = ( 5 x 805 ) / 805

= 5 / 805

= 5

Step3:

LCM(5, 671) = 3355

GCD(5, 671) = ( 5 x 671 ) / 3355

= 5 / 671

= 5

So, Greatest Common Divisor of 685, 575, 805, 671 is 1
