Given numbers are 125, 255, 868, 729

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

Apply this formula for all numbers.

Step1:

LCM(125, 255) = 6375

GCD(125, 255) = ( 125 x 255 ) / 6375

= 125 / 255

= 125

Step2:

LCM(5, 868) = 4340

GCD(5, 868) = ( 5 x 868 ) / 4340

= 5 / 868

= 5

Step3:

LCM(1, 729) = 729

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

= 1 / 729

= 1

So, Greatest Common Divisor of 125, 255, 868, 729 is 1
