Given numbers are 990, 431, 664, 197
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(990, 431) = 426690
GCD(990, 431) = ( 990 x 431 ) / 426690
= 990 / 431
= 990
Step2:
LCM(1, 664) = 664
GCD(1, 664) = ( 1 x 664 ) / 664
= 1 / 664
= 1
Step3:
LCM(1, 197) = 197
GCD(1, 197) = ( 1 x 197 ) / 197
= 1 / 197
= 1
So, Greatest Common Divisor of 990, 431, 664, 197 is 1
