Given numbers are 165, 510, 991, 778

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

Apply this formula for all numbers.

Step1:

LCM(165, 510) = 5610

GCD(165, 510) = ( 165 x 510 ) / 5610

= 165 / 510

= 165

Step2:

LCM(15, 991) = 14865

GCD(15, 991) = ( 15 x 991 ) / 14865

= 15 / 991

= 15

Step3:

LCM(1, 778) = 778

GCD(1, 778) = ( 1 x 778 ) / 778

= 1 / 778

= 1

So, Greatest Common Divisor of 165, 510, 991, 778 is 1
