Given numbers are 821, 179, 447, 248

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

Apply this formula for all numbers.

Step1:

LCM(821, 179) = 146959

GCD(821, 179) = ( 821 x 179 ) / 146959

= 821 / 179

= 821

Step2:

LCM(1, 447) = 447

GCD(1, 447) = ( 1 x 447 ) / 447

= 1 / 447

= 1

Step3:

LCM(1, 248) = 248

GCD(1, 248) = ( 1 x 248 ) / 248

= 1 / 248

= 1

So, Greatest Common Divisor of 821, 179, 447, 248 is 1
