Given numbers are 665, 186, 545, 905

The list of prime factors of all numbers are

Prime factors of 665 are 5 x 7 x 19

Prime factors of 186 are 2 x 3 x 31

Prime factors of 545 are 5 x 109

Prime factors of 905 are 5 x 181

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

Given numbers are 665, 186, 545, 905

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

Apply this formula for all numbers.

Step1:

LCM(665, 186) = 123690

GCD(665, 186) = ( 665 x 186 ) / 123690

= 665 / 186

= 665

Step2:

LCM(1, 545) = 545

GCD(1, 545) = ( 1 x 545 ) / 545

= 1 / 545

= 1

Step3:

LCM(1, 905) = 905

GCD(1, 905) = ( 1 x 905 ) / 905

= 1 / 905

= 1

So, Greatest Common Divisor of 665, 186, 545, 905 is 1
