Given numbers are 772, 172, 663, 783

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

Apply this formula for all numbers.

Step1:

LCM(772, 172) = 33196

GCD(772, 172) = ( 772 x 172 ) / 33196

= 772 / 172

= 772

Step2:

LCM(4, 663) = 2652

GCD(4, 663) = ( 4 x 663 ) / 2652

= 4 / 663

= 4

Step3:

LCM(1, 783) = 783

GCD(1, 783) = ( 1 x 783 ) / 783

= 1 / 783

= 1

So, Greatest Common Divisor of 772, 172, 663, 783 is 1
