Given numbers are 831, 669, 482, 138

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

Apply this formula for all numbers.

Step1:

LCM(831, 669) = 185313

GCD(831, 669) = ( 831 x 669 ) / 185313

= 831 / 669

= 831

Step2:

LCM(3, 482) = 1446

GCD(3, 482) = ( 3 x 482 ) / 1446

= 3 / 482

= 3

Step3:

LCM(1, 138) = 138

GCD(1, 138) = ( 1 x 138 ) / 138

= 1 / 138

= 1

So, Greatest Common Divisor of 831, 669, 482, 138 is 1
