Given numbers are 821, 931, 438, 832

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

Apply this formula for all numbers.

Step1:

LCM(821, 931) = 764351

GCD(821, 931) = ( 821 x 931 ) / 764351

= 821 / 931

= 821

Step2:

LCM(1, 438) = 438

GCD(1, 438) = ( 1 x 438 ) / 438

= 1 / 438

= 1

Step3:

LCM(1, 832) = 832

GCD(1, 832) = ( 1 x 832 ) / 832

= 1 / 832

= 1

So, Greatest Common Divisor of 821, 931, 438, 832 is 1
