Given numbers are 780, 532, 397, 243

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 532 are 2 x 2 x 7 x 19

Prime factors of 397 are 397

Prime factors of 243 are 3 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 780, 532, 397, 243

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

Apply this formula for all numbers.

Step1:

LCM(780, 532) = 103740

GCD(780, 532) = ( 780 x 532 ) / 103740

= 780 / 532

= 780

Step2:

LCM(4, 397) = 1588

GCD(4, 397) = ( 4 x 397 ) / 1588

= 4 / 397

= 4

Step3:

LCM(1, 243) = 243

GCD(1, 243) = ( 1 x 243 ) / 243

= 1 / 243

= 1

So, Greatest Common Divisor of 780, 532, 397, 243 is 1
