The list of prime factors of all numbers are
Prime factors of 515 are 5 x 103
Prime factors of 210 are 2 x 3 x 5 x 7
Prime factors of 154 are 2 x 7 x 11
Prime factors of 500 are 2 x 2 x 5 x 5 x 5
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 515, 210, 154, 500
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(515, 210) = 21630
GCD(515, 210) = ( 515 x 210 ) / 21630
= 515 / 210
= 515
Step2:
LCM(5, 154) = 770
GCD(5, 154) = ( 5 x 154 ) / 770
= 5 / 154
= 5
Step3:
LCM(1, 500) = 500
GCD(1, 500) = ( 1 x 500 ) / 500
= 1 / 500
= 1
So, Greatest Common Divisor of 515, 210, 154, 500 is 1
