The list of prime factors of all numbers are
Prime factors of 814 are 2 x 11 x 37
Prime factors of 680 are 2 x 2 x 2 x 5 x 17
Prime factors of 403 are 13 x 31
Prime factors of 140 are 2 x 2 x 5 x 7
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 814, 680, 403, 140
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(814, 680) = 276760
GCD(814, 680) = ( 814 x 680 ) / 276760
= 814 / 680
= 814
Step2:
LCM(2, 403) = 806
GCD(2, 403) = ( 2 x 403 ) / 806
= 2 / 403
= 2
Step3:
LCM(1, 140) = 140
GCD(1, 140) = ( 1 x 140 ) / 140
= 1 / 140
= 1
So, Greatest Common Divisor of 814, 680, 403, 140 is 1
