Given numbers are 972, 730, 178, 669

The list of prime factors of all numbers are

Prime factors of 972 are 2 x 2 x 3 x 3 x 3 x 3 x 3

Prime factors of 730 are 2 x 5 x 73

Prime factors of 178 are 2 x 89

Prime factors of 669 are 3 x 223

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

Given numbers are 972, 730, 178, 669

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

Apply this formula for all numbers.

Step1:

LCM(972, 730) = 354780

GCD(972, 730) = ( 972 x 730 ) / 354780

= 972 / 730

= 972

Step2:

LCM(2, 178) = 178

GCD(2, 178) = ( 2 x 178 ) / 178

= 2 / 178

= 2

Step3:

LCM(2, 669) = 1338

GCD(2, 669) = ( 2 x 669 ) / 1338

= 2 / 669

= 2

So, Greatest Common Divisor of 972, 730, 178, 669 is 1
