GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(664, 989) = 656696
GCD(664, 989) = ( 664 x 989 ) / 656696
= 664 / 989
= 664
Step2:
LCM(1, 794) = 794
GCD(1, 794) = ( 1 x 794 ) / 794
= 1 / 794
= 1
Step3:
LCM(1, 690) = 690
GCD(1, 690) = ( 1 x 690 ) / 690
= 1 / 690
= 1
So, Greatest Common Divisor of 664, 989, 794, 690 is 1
