Given numbers are 634, 661, 865, 231

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

Apply this formula for all numbers.

Step1:

LCM(634, 661) = 419074

GCD(634, 661) = ( 634 x 661 ) / 419074

= 634 / 661

= 634

Step2:

LCM(1, 865) = 865

GCD(1, 865) = ( 1 x 865 ) / 865

= 1 / 865

= 1

Step3:

LCM(1, 231) = 231

GCD(1, 231) = ( 1 x 231 ) / 231

= 1 / 231

= 1

So, Greatest Common Divisor of 634, 661, 865, 231 is 1
