Given numbers are 153, 780, 762, 161

The list of prime factors of all numbers are

Prime factors of 153 are 3 x 3 x 17

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

Prime factors of 762 are 2 x 3 x 127

Prime factors of 161 are 7 x 23

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

Given numbers are 153, 780, 762, 161

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

Apply this formula for all numbers.

Step1:

LCM(153, 780) = 39780

GCD(153, 780) = ( 153 x 780 ) / 39780

= 153 / 780

= 153

Step2:

LCM(3, 762) = 762

GCD(3, 762) = ( 3 x 762 ) / 762

= 3 / 762

= 3

Step3:

LCM(3, 161) = 483

GCD(3, 161) = ( 3 x 161 ) / 483

= 3 / 161

= 3

So, Greatest Common Divisor of 153, 780, 762, 161 is 1
