Prime factors of 905 are 5 x 181
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 830, 422, 302, 905
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(830, 422) = 175130
GCD(830, 422) = ( 830 x 422 ) / 175130
= 830 / 422
= 830
Step2:
LCM(2, 302) = 302
GCD(2, 302) = ( 2 x 302 ) / 302
= 2 / 302
= 2
Step3:
LCM(2, 905) = 1810
GCD(2, 905) = ( 2 x 905 ) / 1810
= 2 / 905
= 2
So, Greatest Common Divisor of 830, 422, 302, 905 is 1
