Given numbers are 130, 140, 349, 731
The list of prime factors of all numbers are
Prime factors of 130 are 2 x 5 x 13
Prime factors of 140 are 2 x 2 x 5 x 7
Prime factors of 349 are 349
Prime factors of 731 are 17 x 43
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 130, 140, 349, 731
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(130, 140) = 1820
GCD(130, 140) = ( 130 x 140 ) / 1820
= 130 / 140
= 130
Step2:
LCM(10, 349) = 3490
GCD(10, 349) = ( 10 x 349 ) / 3490
= 10 / 349
= 10
Step3:
LCM(1, 731) = 731
GCD(1, 731) = ( 1 x 731 ) / 731
= 1 / 731
= 1
So, Greatest Common Divisor of 130, 140, 349, 731 is 1
