Given numbers are 520, 215, 213, 431
The list of prime factors of all numbers are
Prime factors of 520 are 2 x 2 x 2 x 5 x 13
Prime factors of 215 are 5 x 43
Prime factors of 213 are 3 x 71
Prime factors of 431 are 431
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 520, 215, 213, 431
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(520, 215) = 22360
GCD(520, 215) = ( 520 x 215 ) / 22360
= 520 / 215
= 520
Step2:
LCM(5, 213) = 1065
GCD(5, 213) = ( 5 x 213 ) / 1065
= 5 / 213
= 5
Step3:
LCM(1, 431) = 431
GCD(1, 431) = ( 1 x 431 ) / 431
= 1 / 431
= 1
So, Greatest Common Divisor of 520, 215, 213, 431 is 1
