Given numbers are 345, 377, 644, 141

The list of prime factors of all numbers are

Prime factors of 345 are 3 x 5 x 23

Prime factors of 377 are 13 x 29

Prime factors of 644 are 2 x 2 x 7 x 23

Prime factors of 141 are 3 x 47

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

Given numbers are 345, 377, 644, 141

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

Apply this formula for all numbers.

Step1:

LCM(345, 377) = 130065

GCD(345, 377) = ( 345 x 377 ) / 130065

= 345 / 377

= 345

Step2:

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

Step3:

LCM(1, 141) = 141

GCD(1, 141) = ( 1 x 141 ) / 141

= 1 / 141

= 1

So, Greatest Common Divisor of 345, 377, 644, 141 is 1
