Given numbers are 665, 905, 634, 563

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

Apply this formula for all numbers.

Step1:

LCM(665, 905) = 120365

GCD(665, 905) = ( 665 x 905 ) / 120365

= 665 / 905

= 665

Step2:

LCM(5, 634) = 3170

GCD(5, 634) = ( 5 x 634 ) / 3170

= 5 / 634

= 5

Step3:

LCM(1, 563) = 563

GCD(1, 563) = ( 1 x 563 ) / 563

= 1 / 563

= 1

So, Greatest Common Divisor of 665, 905, 634, 563 is 1
