Given numbers are 780, 324, 564, 745

The list of prime factors of all numbers are

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

Prime factors of 324 are 2 x 2 x 3 x 3 x 3 x 3

Prime factors of 564 are 2 x 2 x 3 x 47

Prime factors of 745 are 5 x 149

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

Given numbers are 780, 324, 564, 745

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

Apply this formula for all numbers.

Step1:

LCM(780, 324) = 21060

GCD(780, 324) = ( 780 x 324 ) / 21060

= 780 / 324

= 780

Step2:

LCM(12, 564) = 564

GCD(12, 564) = ( 12 x 564 ) / 564

= 12 / 564

= 12

Step3:

LCM(12, 745) = 8940

GCD(12, 745) = ( 12 x 745 ) / 8940

= 12 / 745

= 12

So, Greatest Common Divisor of 780, 324, 564, 745 is 1
