Given numbers are 630, 445, 300, 672
The list of prime factors of all numbers are
Prime factors of 630 are 2 x 3 x 3 x 5 x 7
Prime factors of 445 are 5 x 89
Prime factors of 300 are 2 x 2 x 3 x 5 x 5
Prime factors of 672 are 2 x 2 x 2 x 2 x 2 x 3 x 7
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 630, 445, 300, 672
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(630, 445) = 56070
GCD(630, 445) = ( 630 x 445 ) / 56070
= 630 / 445
= 630
Step2:
LCM(5, 300) = 300
GCD(5, 300) = ( 5 x 300 ) / 300
= 5 / 300
= 5
Step3:
LCM(5, 672) = 3360
GCD(5, 672) = ( 5 x 672 ) / 3360
= 5 / 672
= 5
So, Greatest Common Divisor of 630, 445, 300, 672 is 1
