Given numbers are 551, 568, 215, 443

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

Apply this formula for all numbers.

Step1:

LCM(551, 568) = 312968

GCD(551, 568) = ( 551 x 568 ) / 312968

= 551 / 568

= 551

Step2:

LCM(1, 215) = 215

GCD(1, 215) = ( 1 x 215 ) / 215

= 1 / 215

= 1

Step3:

LCM(1, 443) = 443

GCD(1, 443) = ( 1 x 443 ) / 443

= 1 / 443

= 1

So, Greatest Common Divisor of 551, 568, 215, 443 is 1
