Given numbers are 871, 770, 153, 145

The list of prime factors of all numbers are

Prime factors of 871 are 13 x 67

Prime factors of 770 are 2 x 5 x 7 x 11

Prime factors of 153 are 3 x 3 x 17

Prime factors of 145 are 5 x 29

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

Given numbers are 871, 770, 153, 145

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

Apply this formula for all numbers.

Step1:

LCM(871, 770) = 670670

GCD(871, 770) = ( 871 x 770 ) / 670670

= 871 / 770

= 871

Step2:

LCM(1, 153) = 153

GCD(1, 153) = ( 1 x 153 ) / 153

= 1 / 153

= 1

Step3:

LCM(1, 145) = 145

GCD(1, 145) = ( 1 x 145 ) / 145

= 1 / 145

= 1

So, Greatest Common Divisor of 871, 770, 153, 145 is 1
