Given numbers are 815, 550, 822, 630
The list of prime factors of all numbers are
Prime factors of 815 are 5 x 163
Prime factors of 550 are 2 x 5 x 5 x 11
Prime factors of 822 are 2 x 3 x 137
Prime factors of 630 are 2 x 3 x 3 x 5 x 7
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 815, 550, 822, 630
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(815, 550) = 89650
GCD(815, 550) = ( 815 x 550 ) / 89650
= 815 / 550
= 815
Step2:
LCM(5, 822) = 4110
GCD(5, 822) = ( 5 x 822 ) / 4110
= 5 / 822
= 5
Step3:
LCM(1, 630) = 630
GCD(1, 630) = ( 1 x 630 ) / 630
= 1 / 630
= 1
So, Greatest Common Divisor of 815, 550, 822, 630 is 1
