Given numbers are 75, 64, 72, 71
The list of prime factors of all numbers are
Prime factors of 75 are 3 x 5 x 5
Prime factors of 64 are 2 x 2 x 2 x 2 x 2 x 2
Prime factors of 72 are 2 x 2 x 2 x 3 x 3
Prime factors of 71 are 71
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 75, 64, 72, 71
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(75, 64) = 4800
GCD(75, 64) = ( 75 x 64 ) / 4800
= 75 / 64
= 75
Step2:
LCM(1, 72) = 72
GCD(1, 72) = ( 1 x 72 ) / 72
= 1 / 72
= 1
Step3:
LCM(1, 71) = 71
GCD(1, 71) = ( 1 x 71 ) / 71
= 1 / 71
= 1
So, Greatest Common Divisor of 75, 64, 72, 71 is 1
