The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 630, 102, 697, 823
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(630, 102) = 10710
GCD(630, 102) = ( 630 x 102 ) / 10710
= 630 / 102
= 630
Step2:
LCM(6, 697) = 4182
GCD(6, 697) = ( 6 x 697 ) / 4182
= 6 / 697
= 6
Step3:
LCM(1, 823) = 823
GCD(1, 823) = ( 1 x 823 ) / 823
= 1 / 823
= 1
So, Greatest Common Divisor of 630, 102, 697, 823 is 1
