Given numbers are 63, 78, 17, 83
The list of prime factors of all numbers are
Prime factors of 63 are 3 x 3 x 7
Prime factors of 78 are 2 x 3 x 13
Prime factors of 17 are 17
Prime factors of 83 are 83
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 63, 78, 17, 83
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(63, 78) = 1638
GCD(63, 78) = ( 63 x 78 ) / 1638
= 63 / 78
= 63
Step2:
LCM(3, 17) = 51
GCD(3, 17) = ( 3 x 17 ) / 51
= 3 / 17
= 3
Step3:
LCM(1, 83) = 83
GCD(1, 83) = ( 1 x 83 ) / 83
= 1 / 83
= 1
So, Greatest Common Divisor of 63, 78, 17, 83 is 1
