Given numbers are 391, 747, 950, 770

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

Apply this formula for all numbers.

Step1:

LCM(391, 747) = 292077

GCD(391, 747) = ( 391 x 747 ) / 292077

= 391 / 747

= 391

Step2:

LCM(1, 950) = 950

GCD(1, 950) = ( 1 x 950 ) / 950

= 1 / 950

= 1

Step3:

LCM(1, 770) = 770

GCD(1, 770) = ( 1 x 770 ) / 770

= 1 / 770

= 1

So, Greatest Common Divisor of 391, 747, 950, 770 is 1
