Given numbers are 972, 860, 329, 145

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 860 are 2 x 2 x 5 x 43

Prime factors of 329 are 7 x 47

Prime factors of 145 are 5 x 29

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

Given numbers are 972, 860, 329, 145

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

Apply this formula for all numbers.

Step1:

LCM(972, 860) = 208980

GCD(972, 860) = ( 972 x 860 ) / 208980

= 972 / 860

= 972

Step2:

LCM(4, 329) = 1316

GCD(4, 329) = ( 4 x 329 ) / 1316

= 4 / 329

= 4

Step3:

LCM(1, 145) = 145

GCD(1, 145) = ( 1 x 145 ) / 145

= 1 / 145

= 1

So, Greatest Common Divisor of 972, 860, 329, 145 is 1
