Given numbers are 216, 218, 79, 891

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

Apply this formula for all numbers.

Step1:

LCM(216, 218) = 23544

GCD(216, 218) = ( 216 x 218 ) / 23544

= 216 / 218

= 216

Step2:

LCM(2, 79) = 158

GCD(2, 79) = ( 2 x 79 ) / 158

= 2 / 79

= 2

Step3:

LCM(1, 891) = 891

GCD(1, 891) = ( 1 x 891 ) / 891

= 1 / 891

= 1

So, Greatest Common Divisor of 216, 218, 79, 891 is 1
