Given numbers are 855, 153, 243, 622

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

Apply this formula for all numbers.

Step1:

LCM(855, 153) = 14535

GCD(855, 153) = ( 855 x 153 ) / 14535

= 855 / 153

= 855

Step2:

LCM(9, 243) = 243

GCD(9, 243) = ( 9 x 243 ) / 243

= 9 / 243

= 9

Step3:

LCM(9, 622) = 5598

GCD(9, 622) = ( 9 x 622 ) / 5598

= 9 / 622

= 9

So, Greatest Common Divisor of 855, 153, 243, 622 is 1
