Given numbers are 777, 840, 759, 505

The list of prime factors of all numbers are

Prime factors of 777 are 3 x 7 x 37

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 759 are 3 x 11 x 23

Prime factors of 505 are 5 x 101

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

Given numbers are 777, 840, 759, 505

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

Apply this formula for all numbers.

Step1:

LCM(777, 840) = 31080

GCD(777, 840) = ( 777 x 840 ) / 31080

= 777 / 840

= 777

Step2:

LCM(21, 759) = 5313

GCD(21, 759) = ( 21 x 759 ) / 5313

= 21 / 759

= 21

Step3:

LCM(3, 505) = 1515

GCD(3, 505) = ( 3 x 505 ) / 1515

= 3 / 505

= 3

So, Greatest Common Divisor of 777, 840, 759, 505 is 1
