The list of prime factors of all numbers are
Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7
Prime factors of 349 are 349
Prime factors of 140 are 2 x 2 x 5 x 7
Prime factors of 734 are 2 x 367
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 840, 349, 140, 734
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(840, 349) = 293160
GCD(840, 349) = ( 840 x 349 ) / 293160
= 840 / 349
= 840
Step2:
LCM(1, 140) = 140
GCD(1, 140) = ( 1 x 140 ) / 140
= 1 / 140
= 1
Step3:
LCM(1, 734) = 734
GCD(1, 734) = ( 1 x 734 ) / 734
= 1 / 734
= 1
So, Greatest Common Divisor of 840, 349, 140, 734 is 1
