Given numbers are 313, 188, 13, 644
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(313, 188) = 58844
GCD(313, 188) = ( 313 x 188 ) / 58844
= 313 / 188
= 313
Step2:
LCM(1, 13) = 13
GCD(1, 13) = ( 1 x 13 ) / 13
= 1 / 13
= 1
Step3:
LCM(1, 644) = 644
GCD(1, 644) = ( 1 x 644 ) / 644
= 1 / 644
= 1
So, Greatest Common Divisor of 313, 188, 13, 644 is 1
