Given numbers are 987, 878, 741, 636

The list of prime factors of all numbers are

Prime factors of 987 are 3 x 7 x 47

Prime factors of 878 are 2 x 439

Prime factors of 741 are 3 x 13 x 19

Prime factors of 636 are 2 x 2 x 3 x 53

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

Given numbers are 987, 878, 741, 636

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

Apply this formula for all numbers.

Step1:

LCM(987, 878) = 866586

GCD(987, 878) = ( 987 x 878 ) / 866586

= 987 / 878

= 987

Step2:

LCM(1, 741) = 741

GCD(1, 741) = ( 1 x 741 ) / 741

= 1 / 741

= 1

Step3:

LCM(1, 636) = 636

GCD(1, 636) = ( 1 x 636 ) / 636

= 1 / 636

= 1

So, Greatest Common Divisor of 987, 878, 741, 636 is 1
