Given numbers are 161, 610, 780, 122

The list of prime factors of all numbers are

Prime factors of 161 are 7 x 23

Prime factors of 610 are 2 x 5 x 61

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

Prime factors of 122 are 2 x 61

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

Given numbers are 161, 610, 780, 122

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

Apply this formula for all numbers.

Step1:

LCM(161, 610) = 98210

GCD(161, 610) = ( 161 x 610 ) / 98210

= 161 / 610

= 161

Step2:

LCM(1, 780) = 780

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

= 1 / 780

= 1

Step3:

LCM(1, 122) = 122

GCD(1, 122) = ( 1 x 122 ) / 122

= 1 / 122

= 1

So, Greatest Common Divisor of 161, 610, 780, 122 is 1
