Given numbers are 840, 807, 777, 505

The list of prime factors of all numbers are

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

Prime factors of 807 are 3 x 269

Prime factors of 777 are 3 x 7 x 37

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 840, 807, 777, 505

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

Apply this formula for all numbers.

Step1:

LCM(840, 807) = 225960

GCD(840, 807) = ( 840 x 807 ) / 225960

= 840 / 807

= 840

Step2:

LCM(3, 777) = 777

GCD(3, 777) = ( 3 x 777 ) / 777

= 3 / 777

= 3

Step3:

LCM(3, 505) = 1515

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

= 3 / 505

= 3

So, Greatest Common Divisor of 840, 807, 777, 505 is 1
