Given numbers are 189, 447, 802, 798

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

Apply this formula for all numbers.

Step1:

LCM(189, 447) = 28161

GCD(189, 447) = ( 189 x 447 ) / 28161

= 189 / 447

= 189

Step2:

LCM(3, 802) = 2406

GCD(3, 802) = ( 3 x 802 ) / 2406

= 3 / 802

= 3

Step3:

LCM(1, 798) = 798

GCD(1, 798) = ( 1 x 798 ) / 798

= 1 / 798

= 1

So, Greatest Common Divisor of 189, 447, 802, 798 is 1
