Given numbers are 821, 348, 372, 556

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

Apply this formula for all numbers.

Step1:

LCM(821, 348) = 285708

GCD(821, 348) = ( 821 x 348 ) / 285708

= 821 / 348

= 821

Step2:

LCM(1, 372) = 372

GCD(1, 372) = ( 1 x 372 ) / 372

= 1 / 372

= 1

Step3:

LCM(1, 556) = 556

GCD(1, 556) = ( 1 x 556 ) / 556

= 1 / 556

= 1

So, Greatest Common Divisor of 821, 348, 372, 556 is 1
