Given numbers are 666, 690, 670, 897

The list of prime factors of all numbers are

Prime factors of 666 are 2 x 3 x 3 x 37

Prime factors of 690 are 2 x 3 x 5 x 23

Prime factors of 670 are 2 x 5 x 67

Prime factors of 897 are 3 x 13 x 23

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

Given numbers are 666, 690, 670, 897

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

Apply this formula for all numbers.

Step1:

LCM(666, 690) = 76590

GCD(666, 690) = ( 666 x 690 ) / 76590

= 666 / 690

= 666

Step2:

LCM(6, 670) = 2010

GCD(6, 670) = ( 6 x 670 ) / 2010

= 6 / 670

= 6

Step3:

LCM(2, 897) = 1794

GCD(2, 897) = ( 2 x 897 ) / 1794

= 2 / 897

= 2

So, Greatest Common Divisor of 666, 690, 670, 897 is 1
