Given numbers are 539, 858, 20, 658

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

Apply this formula for all numbers.

Step1:

LCM(539, 858) = 42042

GCD(539, 858) = ( 539 x 858 ) / 42042

= 539 / 858

= 539

Step2:

LCM(11, 20) = 220

GCD(11, 20) = ( 11 x 20 ) / 220

= 11 / 20

= 11

Step3:

LCM(1, 658) = 658

GCD(1, 658) = ( 1 x 658 ) / 658

= 1 / 658

= 1

So, Greatest Common Divisor of 539, 858, 20, 658 is 1
