GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(664, 774) = 256968
GCD(664, 774) = ( 664 x 774 ) / 256968
= 664 / 774
= 664
Step2:
LCM(2, 202) = 202
GCD(2, 202) = ( 2 x 202 ) / 202
= 2 / 202
= 2
Step3:
LCM(2, 689) = 1378
GCD(2, 689) = ( 2 x 689 ) / 1378
= 2 / 689
= 2
So, Greatest Common Divisor of 664, 774, 202, 689 is 1
