Given numbers are 855, 180, 995, 450

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

Apply this formula for all numbers.

Step1:

LCM(855, 180) = 3420

GCD(855, 180) = ( 855 x 180 ) / 3420

= 855 / 180

= 855

Step2:

LCM(45, 995) = 8955

GCD(45, 995) = ( 45 x 995 ) / 8955

= 45 / 995

= 45

Step3:

LCM(5, 450) = 450

GCD(5, 450) = ( 5 x 450 ) / 450

= 5 / 450

= 5

So, Greatest Common Divisor of 855, 180, 995, 450 is 5
