Given numbers are 673, 316, 194, 644
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(673, 316) = 212668
GCD(673, 316) = ( 673 x 316 ) / 212668
= 673 / 316
= 673
Step2:
LCM(1, 194) = 194
GCD(1, 194) = ( 1 x 194 ) / 194
= 1 / 194
= 1
Step3:
LCM(1, 644) = 644
GCD(1, 644) = ( 1 x 644 ) / 644
= 1 / 644
= 1
So, Greatest Common Divisor of 673, 316, 194, 644 is 1
