Given numbers are 825, 639, 281, 315

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

Apply this formula for all numbers.

Step1:

LCM(825, 639) = 175725

GCD(825, 639) = ( 825 x 639 ) / 175725

= 825 / 639

= 825

Step2:

LCM(3, 281) = 843

GCD(3, 281) = ( 3 x 281 ) / 843

= 3 / 281

= 3

Step3:

LCM(1, 315) = 315

GCD(1, 315) = ( 1 x 315 ) / 315

= 1 / 315

= 1

So, Greatest Common Divisor of 825, 639, 281, 315 is 1
