Prime factors of 520 are 2 x 2 x 2 x 5 x 13
Prime factors of 651 are 3 x 7 x 31
Prime factors of 231 are 3 x 7 x 11
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 523, 520, 651, 231
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(523, 520) = 271960
GCD(523, 520) = ( 523 x 520 ) / 271960
= 523 / 520
= 523
Step2:
LCM(1, 651) = 651
GCD(1, 651) = ( 1 x 651 ) / 651
= 1 / 651
= 1
Step3:
LCM(1, 231) = 231
GCD(1, 231) = ( 1 x 231 ) / 231
= 1 / 231
= 1
So, Greatest Common Divisor of 523, 520, 651, 231 is 1
