Given numbers are 170, 212, 171, 213
The list of prime factors of all numbers are
Prime factors of 170 are 2 x 5 x 17
Prime factors of 212 are 2 x 2 x 53
Prime factors of 171 are 3 x 3 x 19
Prime factors of 213 are 3 x 71
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 170, 212, 171, 213
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(170, 212) = 18020
GCD(170, 212) = ( 170 x 212 ) / 18020
= 170 / 212
= 170
Step2:
LCM(2, 171) = 342
GCD(2, 171) = ( 2 x 171 ) / 342
= 2 / 171
= 2
Step3:
LCM(1, 213) = 213
GCD(1, 213) = ( 1 x 213 ) / 213
= 1 / 213
= 1
So, Greatest Common Divisor of 170, 212, 171, 213 is 1
