Given numbers are 769, 705, 780, 711

The list of prime factors of all numbers are

Prime factors of 769 are 769

Prime factors of 705 are 3 x 5 x 47

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 711 are 3 x 3 x 79

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 769, 705, 780, 711

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

Apply this formula for all numbers.

Step1:

LCM(769, 705) = 542145

GCD(769, 705) = ( 769 x 705 ) / 542145

= 769 / 705

= 769

Step2:

LCM(1, 780) = 780

GCD(1, 780) = ( 1 x 780 ) / 780

= 1 / 780

= 1

Step3:

LCM(1, 711) = 711

GCD(1, 711) = ( 1 x 711 ) / 711

= 1 / 711

= 1

So, Greatest Common Divisor of 769, 705, 780, 711 is 1
