Given numbers are 965, 531, 40, 780

The list of prime factors of all numbers are

Prime factors of 965 are 5 x 193

Prime factors of 531 are 3 x 3 x 59

Prime factors of 40 are 2 x 2 x 2 x 5

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

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

Given numbers are 965, 531, 40, 780

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

Apply this formula for all numbers.

Step1:

LCM(965, 531) = 512415

GCD(965, 531) = ( 965 x 531 ) / 512415

= 965 / 531

= 965

Step2:

LCM(1, 40) = 40

GCD(1, 40) = ( 1 x 40 ) / 40

= 1 / 40

= 1

Step3:

LCM(1, 780) = 780

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

= 1 / 780

= 1

So, Greatest Common Divisor of 965, 531, 40, 780 is 1
