Given numbers are 313, 639, 629, 821
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(313, 639) = 200007
GCD(313, 639) = ( 313 x 639 ) / 200007
= 313 / 639
= 313
Step2:
LCM(1, 629) = 629
GCD(1, 629) = ( 1 x 629 ) / 629
= 1 / 629
= 1
Step3:
LCM(1, 821) = 821
GCD(1, 821) = ( 1 x 821 ) / 821
= 1 / 821
= 1
So, Greatest Common Divisor of 313, 639, 629, 821 is 1
