Given numbers are 664, 392, 997, 144

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

Apply this formula for all numbers.

Step1:

LCM(664, 392) = 32536

GCD(664, 392) = ( 664 x 392 ) / 32536

= 664 / 392

= 664

Step2:

LCM(8, 997) = 7976

GCD(8, 997) = ( 8 x 997 ) / 7976

= 8 / 997

= 8

Step3:

LCM(1, 144) = 144

GCD(1, 144) = ( 1 x 144 ) / 144

= 1 / 144

= 1

So, Greatest Common Divisor of 664, 392, 997, 144 is 1
