Given numbers are 630, 321, 190, 691
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 321 are 3 x 107
Prime factors of 190 are 2 x 5 x 19
Prime factors of 691 are 691
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 630, 321, 190, 691
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(630, 321) = 67410
GCD(630, 321) = ( 630 x 321 ) / 67410
= 630 / 321
= 630
Step2:
LCM(3, 190) = 570
GCD(3, 190) = ( 3 x 190 ) / 570
= 3 / 190
= 3
Step3:
LCM(1, 691) = 691
GCD(1, 691) = ( 1 x 691 ) / 691
= 1 / 691
= 1
So, Greatest Common Divisor of 630, 321, 190, 691 is 1
