Given numbers are 664, 970, 153, 166
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(664, 970) = 322040
GCD(664, 970) = ( 664 x 970 ) / 322040
= 664 / 970
= 664
Step2:
LCM(2, 153) = 306
GCD(2, 153) = ( 2 x 153 ) / 306
= 2 / 153
= 2
Step3:
LCM(1, 166) = 166
GCD(1, 166) = ( 1 x 166 ) / 166
= 1 / 166
= 1
So, Greatest Common Divisor of 664, 970, 153, 166 is 1
