Given numbers are 416, 545, 769, 778

The list of prime factors of all numbers are

Prime factors of 416 are 2 x 2 x 2 x 2 x 2 x 13

Prime factors of 545 are 5 x 109

Prime factors of 769 are 769

Prime factors of 778 are 2 x 389

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

Given numbers are 416, 545, 769, 778

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

Apply this formula for all numbers.

Step1:

LCM(416, 545) = 226720

GCD(416, 545) = ( 416 x 545 ) / 226720

= 416 / 545

= 416

Step2:

LCM(1, 769) = 769

GCD(1, 769) = ( 1 x 769 ) / 769

= 1 / 769

= 1

Step3:

LCM(1, 778) = 778

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

= 1 / 778

= 1

So, Greatest Common Divisor of 416, 545, 769, 778 is 1
