Given numbers are 782, 434, 232, 391

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

Apply this formula for all numbers.

Step1:

LCM(782, 434) = 169694

GCD(782, 434) = ( 782 x 434 ) / 169694

= 782 / 434

= 782

Step2:

LCM(2, 232) = 232

GCD(2, 232) = ( 2 x 232 ) / 232

= 2 / 232

= 2

Step3:

LCM(2, 391) = 782

GCD(2, 391) = ( 2 x 391 ) / 782

= 2 / 391

= 2

So, Greatest Common Divisor of 782, 434, 232, 391 is 1
