Prime factors of 732 are 2 x 2 x 3 x 61
Prime factors of 445 are 5 x 89
Prime factors of 391 are 17 x 23
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 510, 732, 445, 391
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(510, 732) = 62220
GCD(510, 732) = ( 510 x 732 ) / 62220
= 510 / 732
= 510
Step2:
LCM(6, 445) = 2670
GCD(6, 445) = ( 6 x 445 ) / 2670
= 6 / 445
= 6
Step3:
LCM(1, 391) = 391
GCD(1, 391) = ( 1 x 391 ) / 391
= 1 / 391
= 1
So, Greatest Common Divisor of 510, 732, 445, 391 is 1
