Given numbers are 490, 456, 350, 203
The list of prime factors of all numbers are
Prime factors of 490 are 2 x 5 x 7 x 7
Prime factors of 456 are 2 x 2 x 2 x 3 x 19
Prime factors of 350 are 2 x 5 x 5 x 7
Prime factors of 203 are 7 x 29
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 490, 456, 350, 203
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(490, 456) = 111720
GCD(490, 456) = ( 490 x 456 ) / 111720
= 490 / 456
= 490
Step2:
LCM(2, 350) = 350
GCD(2, 350) = ( 2 x 350 ) / 350
= 2 / 350
= 2
Step3:
LCM(2, 203) = 406
GCD(2, 203) = ( 2 x 203 ) / 406
= 2 / 203
= 2
So, Greatest Common Divisor of 490, 456, 350, 203 is 1
