Given numbers are 987, 705, 802, 168

The list of prime factors of all numbers are

Prime factors of 987 are 3 x 7 x 47

Prime factors of 705 are 3 x 5 x 47

Prime factors of 802 are 2 x 401

Prime factors of 168 are 2 x 2 x 2 x 3 x 7

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

Given numbers are 987, 705, 802, 168

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

Apply this formula for all numbers.

Step1:

LCM(987, 705) = 4935

GCD(987, 705) = ( 987 x 705 ) / 4935

= 987 / 705

= 987

Step2:

LCM(141, 802) = 113082

GCD(141, 802) = ( 141 x 802 ) / 113082

= 141 / 802

= 141

Step3:

LCM(1, 168) = 168

GCD(1, 168) = ( 1 x 168 ) / 168

= 1 / 168

= 1

So, Greatest Common Divisor of 987, 705, 802, 168 is 1
