Given numbers are 858, 786, 257, 549

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

Apply this formula for all numbers.

Step1:

LCM(858, 786) = 112398

GCD(858, 786) = ( 858 x 786 ) / 112398

= 858 / 786

= 858

Step2:

LCM(6, 257) = 1542

GCD(6, 257) = ( 6 x 257 ) / 1542

= 6 / 257

= 6

Step3:

LCM(1, 549) = 549

GCD(1, 549) = ( 1 x 549 ) / 549

= 1 / 549

= 1

So, Greatest Common Divisor of 858, 786, 257, 549 is 1
