Given numbers are 403, 704, 690, 508
The list of prime factors of all numbers are
Prime factors of 403 are 13 x 31
Prime factors of 704 are 2 x 2 x 2 x 2 x 2 x 2 x 11
Prime factors of 690 are 2 x 3 x 5 x 23
Prime factors of 508 are 2 x 2 x 127
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 403, 704, 690, 508
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(403, 704) = 283712
GCD(403, 704) = ( 403 x 704 ) / 283712
= 403 / 704
= 403
Step2:
LCM(1, 690) = 690
GCD(1, 690) = ( 1 x 690 ) / 690
= 1 / 690
= 1
Step3:
LCM(1, 508) = 508
GCD(1, 508) = ( 1 x 508 ) / 508
= 1 / 508
= 1
So, Greatest Common Divisor of 403, 704, 690, 508 is 1
