Given numbers are 970, 945, 987, 787

The list of prime factors of all numbers are

Prime factors of 970 are 2 x 5 x 97

Prime factors of 945 are 3 x 3 x 3 x 5 x 7

Prime factors of 987 are 3 x 7 x 47

Prime factors of 787 are 787

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

Given numbers are 970, 945, 987, 787

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

Apply this formula for all numbers.

Step1:

LCM(970, 945) = 183330

GCD(970, 945) = ( 970 x 945 ) / 183330

= 970 / 945

= 970

Step2:

LCM(5, 987) = 4935

GCD(5, 987) = ( 5 x 987 ) / 4935

= 5 / 987

= 5

Step3:

LCM(1, 787) = 787

GCD(1, 787) = ( 1 x 787 ) / 787

= 1 / 787

= 1

So, Greatest Common Divisor of 970, 945, 987, 787 is 1
