Given numbers are 551, 172, 885, 280

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

Apply this formula for all numbers.

Step1:

LCM(551, 172) = 94772

GCD(551, 172) = ( 551 x 172 ) / 94772

= 551 / 172

= 551

Step2:

LCM(1, 885) = 885

GCD(1, 885) = ( 1 x 885 ) / 885

= 1 / 885

= 1

Step3:

LCM(1, 280) = 280

GCD(1, 280) = ( 1 x 280 ) / 280

= 1 / 280

= 1

So, Greatest Common Divisor of 551, 172, 885, 280 is 1
