Given numbers are 843, 687, 749, 646

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

Apply this formula for all numbers.

Step1:

LCM(843, 687) = 193047

GCD(843, 687) = ( 843 x 687 ) / 193047

= 843 / 687

= 843

Step2:

LCM(3, 749) = 2247

GCD(3, 749) = ( 3 x 749 ) / 2247

= 3 / 749

= 3

Step3:

LCM(1, 646) = 646

GCD(1, 646) = ( 1 x 646 ) / 646

= 1 / 646

= 1

So, Greatest Common Divisor of 843, 687, 749, 646 is 1
