Given numbers are 690, 545, 344, 871

The list of prime factors of all numbers are

Prime factors of 690 are 2 x 3 x 5 x 23

Prime factors of 545 are 5 x 109

Prime factors of 344 are 2 x 2 x 2 x 43

Prime factors of 871 are 13 x 67

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

Given numbers are 690, 545, 344, 871

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

Apply this formula for all numbers.

Step1:

LCM(690, 545) = 75210

GCD(690, 545) = ( 690 x 545 ) / 75210

= 690 / 545

= 690

Step2:

LCM(5, 344) = 1720

GCD(5, 344) = ( 5 x 344 ) / 1720

= 5 / 344

= 5

Step3:

LCM(1, 871) = 871

GCD(1, 871) = ( 1 x 871 ) / 871

= 1 / 871

= 1

So, Greatest Common Divisor of 690, 545, 344, 871 is 1
