Given numbers are 782, 414, 393, 689

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

Apply this formula for all numbers.

Step1:

LCM(782, 414) = 7038

GCD(782, 414) = ( 782 x 414 ) / 7038

= 782 / 414

= 782

Step2:

LCM(46, 393) = 18078

GCD(46, 393) = ( 46 x 393 ) / 18078

= 46 / 393

= 46

Step3:

LCM(1, 689) = 689

GCD(1, 689) = ( 1 x 689 ) / 689

= 1 / 689

= 1

So, Greatest Common Divisor of 782, 414, 393, 689 is 1
