Given numbers are 778, 784, 575, 648

The list of prime factors of all numbers are

Prime factors of 778 are 2 x 389

Prime factors of 784 are 2 x 2 x 2 x 2 x 7 x 7

Prime factors of 575 are 5 x 5 x 23

Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3

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

Given numbers are 778, 784, 575, 648

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

Apply this formula for all numbers.

Step1:

LCM(778, 784) = 304976

GCD(778, 784) = ( 778 x 784 ) / 304976

= 778 / 784

= 778

Step2:

LCM(2, 575) = 1150

GCD(2, 575) = ( 2 x 575 ) / 1150

= 2 / 575

= 2

Step3:

LCM(1, 648) = 648

GCD(1, 648) = ( 1 x 648 ) / 648

= 1 / 648

= 1

So, Greatest Common Divisor of 778, 784, 575, 648 is 1
