Given numbers are 301, 188, 306, 490
The list of prime factors of all numbers are
Prime factors of 301 are 7 x 43
Prime factors of 188 are 2 x 2 x 47
Prime factors of 306 are 2 x 3 x 3 x 17
Prime factors of 490 are 2 x 5 x 7 x 7
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 301, 188, 306, 490
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(301, 188) = 56588
GCD(301, 188) = ( 301 x 188 ) / 56588
= 301 / 188
= 301
Step2:
LCM(1, 306) = 306
GCD(1, 306) = ( 1 x 306 ) / 306
= 1 / 306
= 1
Step3:
LCM(1, 490) = 490
GCD(1, 490) = ( 1 x 490 ) / 490
= 1 / 490
= 1
So, Greatest Common Divisor of 301, 188, 306, 490 is 1
