Given numbers are 843, 365, 131, 780

The list of prime factors of all numbers are

Prime factors of 843 are 3 x 281

Prime factors of 365 are 5 x 73

Prime factors of 131 are 131

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 843, 365, 131, 780

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

Apply this formula for all numbers.

Step1:

LCM(843, 365) = 307695

GCD(843, 365) = ( 843 x 365 ) / 307695

= 843 / 365

= 843

Step2:

LCM(1, 131) = 131

GCD(1, 131) = ( 1 x 131 ) / 131

= 1 / 131

= 1

Step3:

LCM(1, 780) = 780

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

= 1 / 780

= 1

So, Greatest Common Divisor of 843, 365, 131, 780 is 1
