Given numbers are 828, 447, 79, 381

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

Apply this formula for all numbers.

Step1:

LCM(828, 447) = 123372

GCD(828, 447) = ( 828 x 447 ) / 123372

= 828 / 447

= 828

Step2:

LCM(3, 79) = 237

GCD(3, 79) = ( 3 x 79 ) / 237

= 3 / 79

= 3

Step3:

LCM(1, 381) = 381

GCD(1, 381) = ( 1 x 381 ) / 381

= 1 / 381

= 1

So, Greatest Common Divisor of 828, 447, 79, 381 is 1
