Given numbers are 201, 987, 187, 840

The list of prime factors of all numbers are

Prime factors of 201 are 3 x 67

Prime factors of 987 are 3 x 7 x 47

Prime factors of 187 are 11 x 17

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

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

Given numbers are 201, 987, 187, 840

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

Apply this formula for all numbers.

Step1:

LCM(201, 987) = 66129

GCD(201, 987) = ( 201 x 987 ) / 66129

= 201 / 987

= 201

Step2:

LCM(3, 187) = 561

GCD(3, 187) = ( 3 x 187 ) / 561

= 3 / 187

= 3

Step3:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1

So, Greatest Common Divisor of 201, 987, 187, 840 is 1
