Given numbers are 810, 292, 210, 531
The list of prime factors of all numbers are
Prime factors of 810 are 2 x 3 x 3 x 3 x 3 x 5
Prime factors of 292 are 2 x 2 x 73
Prime factors of 210 are 2 x 3 x 5 x 7
Prime factors of 531 are 3 x 3 x 59
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 810, 292, 210, 531
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(810, 292) = 118260
GCD(810, 292) = ( 810 x 292 ) / 118260
= 810 / 292
= 810
Step2:
LCM(2, 210) = 210
GCD(2, 210) = ( 2 x 210 ) / 210
= 2 / 210
= 2
Step3:
LCM(2, 531) = 1062
GCD(2, 531) = ( 2 x 531 ) / 1062
= 2 / 531
= 2
So, Greatest Common Divisor of 810, 292, 210, 531 is 1
