Given numbers are 855, 375, 45, 636

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

Apply this formula for all numbers.

Step1:

LCM(855, 375) = 21375

GCD(855, 375) = ( 855 x 375 ) / 21375

= 855 / 375

= 855

Step2:

LCM(15, 45) = 45

GCD(15, 45) = ( 15 x 45 ) / 45

= 15 / 45

= 15

Step3:

LCM(15, 636) = 3180

GCD(15, 636) = ( 15 x 636 ) / 3180

= 15 / 636

= 15

So, Greatest Common Divisor of 855, 375, 45, 636 is 3
