Given numbers are 329, 973, 670, 639
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(329, 973) = 45731
GCD(329, 973) = ( 329 x 973 ) / 45731
= 329 / 973
= 329
Step2:
LCM(7, 670) = 4690
GCD(7, 670) = ( 7 x 670 ) / 4690
= 7 / 670
= 7
Step3:
LCM(1, 639) = 639
GCD(1, 639) = ( 1 x 639 ) / 639
= 1 / 639
= 1
So, Greatest Common Divisor of 329, 973, 670, 639 is 1
