Given numbers are 685, 410, 427, 291

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

Apply this formula for all numbers.

Step1:

LCM(685, 410) = 56170

GCD(685, 410) = ( 685 x 410 ) / 56170

= 685 / 410

= 685

Step2:

LCM(5, 427) = 2135

GCD(5, 427) = ( 5 x 427 ) / 2135

= 5 / 427

= 5

Step3:

LCM(1, 291) = 291

GCD(1, 291) = ( 1 x 291 ) / 291

= 1 / 291

= 1

So, Greatest Common Divisor of 685, 410, 427, 291 is 1
