Given numbers are 551, 642, 849

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

Apply this formula for all numbers.

Step1:

LCM(551, 642) = 353742

GCD(551, 642) = ( 551 x 642 ) / 353742

= 551 / 642

= 551

Step2:

LCM(1, 849) = 849

GCD(1, 849) = ( 1 x 849 ) / 849

= 1 / 849

= 1

So, Greatest Common Divisor of 551, 642, 849 is 1
