Given numbers are 855, 243, 742, 892

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

Apply this formula for all numbers.

Step1:

LCM(855, 243) = 23085

GCD(855, 243) = ( 855 x 243 ) / 23085

= 855 / 243

= 855

Step2:

LCM(9, 742) = 6678

GCD(9, 742) = ( 9 x 742 ) / 6678

= 9 / 742

= 9

Step3:

LCM(1, 892) = 892

GCD(1, 892) = ( 1 x 892 ) / 892

= 1 / 892

= 1

So, Greatest Common Divisor of 855, 243, 742, 892 is 1
