Given numbers are 778, 545, 453, 480

The list of prime factors of all numbers are

Prime factors of 778 are 2 x 389

Prime factors of 545 are 5 x 109

Prime factors of 453 are 3 x 151

Prime factors of 480 are 2 x 2 x 2 x 2 x 2 x 3 x 5

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

Given numbers are 778, 545, 453, 480

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

Apply this formula for all numbers.

Step1:

LCM(778, 545) = 424010

GCD(778, 545) = ( 778 x 545 ) / 424010

= 778 / 545

= 778

Step2:

LCM(1, 453) = 453

GCD(1, 453) = ( 1 x 453 ) / 453

= 1 / 453

= 1

Step3:

LCM(1, 480) = 480

GCD(1, 480) = ( 1 x 480 ) / 480

= 1 / 480

= 1

So, Greatest Common Divisor of 778, 545, 453, 480 is 1
