Prime factors of 810 are 2 x 3 x 3 x 3 x 3 x 5
Prime factors of 678 are 2 x 3 x 113
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 865, 147, 810, 678
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(865, 147) = 127155
GCD(865, 147) = ( 865 x 147 ) / 127155
= 865 / 147
= 865
Step2:
LCM(1, 810) = 810
GCD(1, 810) = ( 1 x 810 ) / 810
= 1 / 810
= 1
Step3:
LCM(1, 678) = 678
GCD(1, 678) = ( 1 x 678 ) / 678
= 1 / 678
= 1
So, Greatest Common Divisor of 865, 147, 810, 678 is 1
