Given numbers are 218, 898, 644, 997

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

Apply this formula for all numbers.

Step1:

LCM(218, 898) = 97882

GCD(218, 898) = ( 218 x 898 ) / 97882

= 218 / 898

= 218

Step2:

LCM(2, 644) = 644

GCD(2, 644) = ( 2 x 644 ) / 644

= 2 / 644

= 2

Step3:

LCM(2, 997) = 1994

GCD(2, 997) = ( 2 x 997 ) / 1994

= 2 / 997

= 2

So, Greatest Common Divisor of 218, 898, 644, 997 is 1
