Given numbers are 665, 357, 705, 975

The list of prime factors of all numbers are

Prime factors of 665 are 5 x 7 x 19

Prime factors of 357 are 3 x 7 x 17

Prime factors of 705 are 3 x 5 x 47

Prime factors of 975 are 3 x 5 x 5 x 13

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

Given numbers are 665, 357, 705, 975

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

Apply this formula for all numbers.

Step1:

LCM(665, 357) = 33915

GCD(665, 357) = ( 665 x 357 ) / 33915

= 665 / 357

= 665

Step2:

LCM(7, 705) = 4935

GCD(7, 705) = ( 7 x 705 ) / 4935

= 7 / 705

= 7

Step3:

LCM(1, 975) = 975

GCD(1, 975) = ( 1 x 975 ) / 975

= 1 / 975

= 1

So, Greatest Common Divisor of 665, 357, 705, 975 is 1
