Given numbers are 57, 40, 58, 64
The list of prime factors of all numbers are
Prime factors of 57 are 3 x 19
Prime factors of 40 are 2 x 2 x 2 x 5
Prime factors of 58 are 2 x 29
Prime factors of 64 are 2 x 2 x 2 x 2 x 2 x 2
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 57, 40, 58, 64
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(57, 40) = 2280
GCD(57, 40) = ( 57 x 40 ) / 2280
= 57 / 40
= 57
Step2:
LCM(1, 58) = 58
GCD(1, 58) = ( 1 x 58 ) / 58
= 1 / 58
= 1
Step3:
LCM(1, 64) = 64
GCD(1, 64) = ( 1 x 64 ) / 64
= 1 / 64
= 1
So, Greatest Common Divisor of 57, 40, 58, 64 is 1
