Given numbers are 379, 145, 780, 648

The list of prime factors of all numbers are

Prime factors of 379 are 379

Prime factors of 145 are 5 x 29

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

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 379, 145, 780, 648

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

Apply this formula for all numbers.

Step1:

LCM(379, 145) = 54955

GCD(379, 145) = ( 379 x 145 ) / 54955

= 379 / 145

= 379

Step2:

LCM(1, 780) = 780

GCD(1, 780) = ( 1 x 780 ) / 780

= 1 / 780

= 1

Step3:

LCM(1, 648) = 648

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

= 1 / 648

= 1

So, Greatest Common Divisor of 379, 145, 780, 648 is 1
