Given numbers are 665, 354, 670, 861

The list of prime factors of all numbers are

Prime factors of 665 are 5 x 7 x 19

Prime factors of 354 are 2 x 3 x 59

Prime factors of 670 are 2 x 5 x 67

Prime factors of 861 are 3 x 7 x 41

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

Given numbers are 665, 354, 670, 861

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

Apply this formula for all numbers.

Step1:

LCM(665, 354) = 235410

GCD(665, 354) = ( 665 x 354 ) / 235410

= 665 / 354

= 665

Step2:

LCM(1, 670) = 670

GCD(1, 670) = ( 1 x 670 ) / 670

= 1 / 670

= 1

Step3:

LCM(1, 861) = 861

GCD(1, 861) = ( 1 x 861 ) / 861

= 1 / 861

= 1

So, Greatest Common Divisor of 665, 354, 670, 861 is 1
