Given numbers are 810, 101, 868, 630
The list of prime factors of all numbers are
Prime factors of 810 are 2 x 3 x 3 x 3 x 3 x 5
Prime factors of 101 are 101
Prime factors of 868 are 2 x 2 x 7 x 31
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 810, 101, 868, 630
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(810, 101) = 81810
GCD(810, 101) = ( 810 x 101 ) / 81810
= 810 / 101
= 810
Step2:
LCM(1, 868) = 868
GCD(1, 868) = ( 1 x 868 ) / 868
= 1 / 868
= 1
Step3:
LCM(1, 630) = 630
GCD(1, 630) = ( 1 x 630 ) / 630
= 1 / 630
= 1
So, Greatest Common Divisor of 810, 101, 868, 630 is 1
