Given numbers are 551, 646, 983, 353

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

Apply this formula for all numbers.

Step1:

LCM(551, 646) = 18734

GCD(551, 646) = ( 551 x 646 ) / 18734

= 551 / 646

= 551

Step2:

LCM(19, 983) = 18677

GCD(19, 983) = ( 19 x 983 ) / 18677

= 19 / 983

= 19

Step3:

LCM(1, 353) = 353

GCD(1, 353) = ( 1 x 353 ) / 353

= 1 / 353

= 1

So, Greatest Common Divisor of 551, 646, 983, 353 is 1
