Given numbers are 855, 665, 609, 141

The list of prime factors of all numbers are

Prime factors of 855 are 3 x 3 x 5 x 19

Prime factors of 665 are 5 x 7 x 19

Prime factors of 609 are 3 x 7 x 29

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 855, 665, 609, 141

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

Apply this formula for all numbers.

Step1:

LCM(855, 665) = 5985

GCD(855, 665) = ( 855 x 665 ) / 5985

= 855 / 665

= 855

Step2:

LCM(95, 609) = 57855

GCD(95, 609) = ( 95 x 609 ) / 57855

= 95 / 609

= 95

Step3:

LCM(1, 141) = 141

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

= 1 / 141

= 1

So, Greatest Common Divisor of 855, 665, 609, 141 is 1
