Given numbers are 693, 342, 970, 978

The list of prime factors of all numbers are

Prime factors of 693 are 3 x 3 x 7 x 11

Prime factors of 342 are 2 x 3 x 3 x 19

Prime factors of 970 are 2 x 5 x 97

Prime factors of 978 are 2 x 3 x 163

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

Given numbers are 693, 342, 970, 978

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

Apply this formula for all numbers.

Step1:

LCM(693, 342) = 26334

GCD(693, 342) = ( 693 x 342 ) / 26334

= 693 / 342

= 693

Step2:

LCM(9, 970) = 8730

GCD(9, 970) = ( 9 x 970 ) / 8730

= 9 / 970

= 9

Step3:

LCM(1, 978) = 978

GCD(1, 978) = ( 1 x 978 ) / 978

= 1 / 978

= 1

So, Greatest Common Divisor of 693, 342, 970, 978 is 1
