Given numbers are 243, 549, 842, 654

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

Apply this formula for all numbers.

Step1:

LCM(243, 549) = 14823

GCD(243, 549) = ( 243 x 549 ) / 14823

= 243 / 549

= 243

Step2:

LCM(9, 842) = 7578

GCD(9, 842) = ( 9 x 842 ) / 7578

= 9 / 842

= 9

Step3:

LCM(1, 654) = 654

GCD(1, 654) = ( 1 x 654 ) / 654

= 1 / 654

= 1

So, Greatest Common Divisor of 243, 549, 842, 654 is 1
