Given numbers are 831, 213, 628, 219

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

Apply this formula for all numbers.

Step1:

LCM(831, 213) = 59001

GCD(831, 213) = ( 831 x 213 ) / 59001

= 831 / 213

= 831

Step2:

LCM(3, 628) = 1884

GCD(3, 628) = ( 3 x 628 ) / 1884

= 3 / 628

= 3

Step3:

LCM(1, 219) = 219

GCD(1, 219) = ( 1 x 219 ) / 219

= 1 / 219

= 1

So, Greatest Common Divisor of 831, 213, 628, 219 is 1
