Given numbers are 847, 987, 831, 669

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

Apply this formula for all numbers.

Step1:

LCM(847, 987) = 119427

GCD(847, 987) = ( 847 x 987 ) / 119427

= 847 / 987

= 847

Step2:

LCM(7, 831) = 5817

GCD(7, 831) = ( 7 x 831 ) / 5817

= 7 / 831

= 7

Step3:

LCM(1, 669) = 669

GCD(1, 669) = ( 1 x 669 ) / 669

= 1 / 669

= 1

So, Greatest Common Divisor of 847, 987, 831, 669 is 1
