Given numbers are 661, 637, 839, 854

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

Apply this formula for all numbers.

Step1:

LCM(661, 637) = 421057

GCD(661, 637) = ( 661 x 637 ) / 421057

= 661 / 637

= 661

Step2:

LCM(1, 839) = 839

GCD(1, 839) = ( 1 x 839 ) / 839

= 1 / 839

= 1

Step3:

LCM(1, 854) = 854

GCD(1, 854) = ( 1 x 854 ) / 854

= 1 / 854

= 1

So, Greatest Common Divisor of 661, 637, 839, 854 is 1
