Given numbers are 961, 669, 320, 771

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

Apply this formula for all numbers.

Step1:

LCM(961, 669) = 642909

GCD(961, 669) = ( 961 x 669 ) / 642909

= 961 / 669

= 961

Step2:

LCM(1, 320) = 320

GCD(1, 320) = ( 1 x 320 ) / 320

= 1 / 320

= 1

Step3:

LCM(1, 771) = 771

GCD(1, 771) = ( 1 x 771 ) / 771

= 1 / 771

= 1

So, Greatest Common Divisor of 961, 669, 320, 771 is 1
