Prime factors of 286 are 2 x 11 x 13
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 105, 321, 694, 286
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(105, 321) = 11235
GCD(105, 321) = ( 105 x 321 ) / 11235
= 105 / 321
= 105
Step2:
LCM(3, 694) = 2082
GCD(3, 694) = ( 3 x 694 ) / 2082
= 3 / 694
= 3
Step3:
LCM(1, 286) = 286
GCD(1, 286) = ( 1 x 286 ) / 286
= 1 / 286
= 1
So, Greatest Common Divisor of 105, 321, 694, 286 is 1
