Given numbers are 772, 842, 120, 666

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

Apply this formula for all numbers.

Step1:

LCM(772, 842) = 325012

GCD(772, 842) = ( 772 x 842 ) / 325012

= 772 / 842

= 772

Step2:

LCM(2, 120) = 120

GCD(2, 120) = ( 2 x 120 ) / 120

= 2 / 120

= 2

Step3:

LCM(2, 666) = 666

GCD(2, 666) = ( 2 x 666 ) / 666

= 2 / 666

= 2

So, Greatest Common Divisor of 772, 842, 120, 666 is 2
