Given numbers are 115, 161, 777, 545

The list of prime factors of all numbers are

Prime factors of 115 are 5 x 23

Prime factors of 161 are 7 x 23

Prime factors of 777 are 3 x 7 x 37

Prime factors of 545 are 5 x 109

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

Given numbers are 115, 161, 777, 545

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

Apply this formula for all numbers.

Step1:

LCM(115, 161) = 805

GCD(115, 161) = ( 115 x 161 ) / 805

= 115 / 161

= 115

Step2:

LCM(23, 777) = 17871

GCD(23, 777) = ( 23 x 777 ) / 17871

= 23 / 777

= 23

Step3:

LCM(1, 545) = 545

GCD(1, 545) = ( 1 x 545 ) / 545

= 1 / 545

= 1

So, Greatest Common Divisor of 115, 161, 777, 545 is 1
