Given numbers are 312, 403, 215, 660
The list of prime factors of all numbers are
Prime factors of 312 are 2 x 2 x 2 x 3 x 13
Prime factors of 403 are 13 x 31
Prime factors of 215 are 5 x 43
Prime factors of 660 are 2 x 2 x 3 x 5 x 11
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 312, 403, 215, 660
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(312, 403) = 9672
GCD(312, 403) = ( 312 x 403 ) / 9672
= 312 / 403
= 312
Step2:
LCM(13, 215) = 2795
GCD(13, 215) = ( 13 x 215 ) / 2795
= 13 / 215
= 13
Step3:
LCM(1, 660) = 660
GCD(1, 660) = ( 1 x 660 ) / 660
= 1 / 660
= 1
So, Greatest Common Divisor of 312, 403, 215, 660 is 1
