Given numbers are 782, 874, 581, 398

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

Apply this formula for all numbers.

Step1:

LCM(782, 874) = 14858

GCD(782, 874) = ( 782 x 874 ) / 14858

= 782 / 874

= 782

Step2:

LCM(46, 581) = 26726

GCD(46, 581) = ( 46 x 581 ) / 26726

= 46 / 581

= 46

Step3:

LCM(1, 398) = 398

GCD(1, 398) = ( 1 x 398 ) / 398

= 1 / 398

= 1

So, Greatest Common Divisor of 782, 874, 581, 398 is 1
