Given numbers are 646, 465, 991, 273

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

Apply this formula for all numbers.

Step1:

LCM(646, 465) = 300390

GCD(646, 465) = ( 646 x 465 ) / 300390

= 646 / 465

= 646

Step2:

LCM(1, 991) = 991

GCD(1, 991) = ( 1 x 991 ) / 991

= 1 / 991

= 1

Step3:

LCM(1, 273) = 273

GCD(1, 273) = ( 1 x 273 ) / 273

= 1 / 273

= 1

So, Greatest Common Divisor of 646, 465, 991, 273 is 1
