Given numbers are 972, 387, 487, 133

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 387 are 3 x 3 x 43

Prime factors of 487 are 487

Prime factors of 133 are 7 x 19

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

Given numbers are 972, 387, 487, 133

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

Apply this formula for all numbers.

Step1:

LCM(972, 387) = 41796

GCD(972, 387) = ( 972 x 387 ) / 41796

= 972 / 387

= 972

Step2:

LCM(9, 487) = 4383

GCD(9, 487) = ( 9 x 487 ) / 4383

= 9 / 487

= 9

Step3:

LCM(1, 133) = 133

GCD(1, 133) = ( 1 x 133 ) / 133

= 1 / 133

= 1

So, Greatest Common Divisor of 972, 387, 487, 133 is 1
