Prime factors of 211 are 211
Prime factors of 394 are 2 x 197
Prime factors of 386 are 2 x 193
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 840, 211, 394, 386
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(840, 211) = 177240
GCD(840, 211) = ( 840 x 211 ) / 177240
= 840 / 211
= 840
Step2:
LCM(1, 394) = 394
GCD(1, 394) = ( 1 x 394 ) / 394
= 1 / 394
= 1
Step3:
LCM(1, 386) = 386
GCD(1, 386) = ( 1 x 386 ) / 386
= 1 / 386
= 1
So, Greatest Common Divisor of 840, 211, 394, 386 is 1
