Given numbers are 847, 189, 393, 603

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

Apply this formula for all numbers.

Step1:

LCM(847, 189) = 22869

GCD(847, 189) = ( 847 x 189 ) / 22869

= 847 / 189

= 847

Step2:

LCM(7, 393) = 2751

GCD(7, 393) = ( 7 x 393 ) / 2751

= 7 / 393

= 7

Step3:

LCM(1, 603) = 603

GCD(1, 603) = ( 1 x 603 ) / 603

= 1 / 603

= 1

So, Greatest Common Divisor of 847, 189, 393, 603 is 1
