Given numbers are 664, 838, 898, 243

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

Apply this formula for all numbers.

Step1:

LCM(664, 838) = 278216

GCD(664, 838) = ( 664 x 838 ) / 278216

= 664 / 838

= 664

Step2:

LCM(2, 898) = 898

GCD(2, 898) = ( 2 x 898 ) / 898

= 2 / 898

= 2

Step3:

LCM(2, 243) = 486

GCD(2, 243) = ( 2 x 243 ) / 486

= 2 / 243

= 2

So, Greatest Common Divisor of 664, 838, 898, 243 is 1
