Given numbers are 215, 510, 20, 899

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

Apply this formula for all numbers.

Step1:

LCM(215, 510) = 21930

GCD(215, 510) = ( 215 x 510 ) / 21930

= 215 / 510

= 215

Step2:

LCM(5, 20) = 20

GCD(5, 20) = ( 5 x 20 ) / 20

= 5 / 20

= 5

Step3:

LCM(5, 899) = 4495

GCD(5, 899) = ( 5 x 899 ) / 4495

= 5 / 899

= 5

So, Greatest Common Divisor of 215, 510, 20, 899 is 1
