Given numbers are 664, 342, 13, 990
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(664, 342) = 113544
GCD(664, 342) = ( 664 x 342 ) / 113544
= 664 / 342
= 664
Step2:
LCM(2, 13) = 26
GCD(2, 13) = ( 2 x 13 ) / 26
= 2 / 13
= 2
Step3:
LCM(1, 990) = 990
GCD(1, 990) = ( 1 x 990 ) / 990
= 1 / 990
= 1
So, Greatest Common Divisor of 664, 342, 13, 990 is 1
