Given numbers are 858, 676, 257, 729

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

Apply this formula for all numbers.

Step1:

LCM(858, 676) = 22308

GCD(858, 676) = ( 858 x 676 ) / 22308

= 858 / 676

= 858

Step2:

LCM(26, 257) = 6682

GCD(26, 257) = ( 26 x 257 ) / 6682

= 26 / 257

= 26

Step3:

LCM(1, 729) = 729

GCD(1, 729) = ( 1 x 729 ) / 729

= 1 / 729

= 1

So, Greatest Common Divisor of 858, 676, 257, 729 is 1
