Given numbers are 531, 698, 656, 780

The list of prime factors of all numbers are

Prime factors of 531 are 3 x 3 x 59

Prime factors of 698 are 2 x 349

Prime factors of 656 are 2 x 2 x 2 x 2 x 41

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 531, 698, 656, 780

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

Apply this formula for all numbers.

Step1:

LCM(531, 698) = 370638

GCD(531, 698) = ( 531 x 698 ) / 370638

= 531 / 698

= 531

Step2:

LCM(1, 656) = 656

GCD(1, 656) = ( 1 x 656 ) / 656

= 1 / 656

= 1

Step3:

LCM(1, 780) = 780

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

= 1 / 780

= 1

So, Greatest Common Divisor of 531, 698, 656, 780 is 1
