GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(318, 620) = 98580
GCD(318, 620) = ( 318 x 620 ) / 98580
= 318 / 620
= 318
Step2:
LCM(2, 949) = 1898
GCD(2, 949) = ( 2 x 949 ) / 1898
= 2 / 949
= 2
Step3:
LCM(1, 639) = 639
GCD(1, 639) = ( 1 x 639 ) / 639
= 1 / 639
= 1
So, Greatest Common Divisor of 318, 620, 949, 639 is 1
