Given numbers are 551, 628, 147, 287

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

Apply this formula for all numbers.

Step1:

LCM(551, 628) = 346028

GCD(551, 628) = ( 551 x 628 ) / 346028

= 551 / 628

= 551

Step2:

LCM(1, 147) = 147

GCD(1, 147) = ( 1 x 147 ) / 147

= 1 / 147

= 1

Step3:

LCM(1, 287) = 287

GCD(1, 287) = ( 1 x 287 ) / 287

= 1 / 287

= 1

So, Greatest Common Divisor of 551, 628, 147, 287 is 1
