Given numbers are 843, 258, 777, 490

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

Apply this formula for all numbers.

Step1:

LCM(843, 258) = 72498

GCD(843, 258) = ( 843 x 258 ) / 72498

= 843 / 258

= 843

Step2:

LCM(3, 777) = 777

GCD(3, 777) = ( 3 x 777 ) / 777

= 3 / 777

= 3

Step3:

LCM(3, 490) = 1470

GCD(3, 490) = ( 3 x 490 ) / 1470

= 3 / 490

= 3

So, Greatest Common Divisor of 843, 258, 777, 490 is 1
