Given numbers are 772, 645, 719, 661

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

Apply this formula for all numbers.

Step1:

LCM(772, 645) = 497940

GCD(772, 645) = ( 772 x 645 ) / 497940

= 772 / 645

= 772

Step2:

LCM(1, 719) = 719

GCD(1, 719) = ( 1 x 719 ) / 719

= 1 / 719

= 1

Step3:

LCM(1, 661) = 661

GCD(1, 661) = ( 1 x 661 ) / 661

= 1 / 661

= 1

So, Greatest Common Divisor of 772, 645, 719, 661 is 1
