Given numbers are 548, 208, 856, 858

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

Apply this formula for all numbers.

Step1:

LCM(548, 208) = 28496

GCD(548, 208) = ( 548 x 208 ) / 28496

= 548 / 208

= 548

Step2:

LCM(4, 856) = 856

GCD(4, 856) = ( 4 x 856 ) / 856

= 4 / 856

= 4

Step3:

LCM(4, 858) = 1716

GCD(4, 858) = ( 4 x 858 ) / 1716

= 4 / 858

= 4

So, Greatest Common Divisor of 548, 208, 856, 858 is 2
