The list of prime factors of all numbers are
Prime factors of 938 are 2 x 7 x 67
Prime factors of 460 are 2 x 2 x 5 x 23
Prime factors of 215 are 5 x 43
Prime factors of 680 are 2 x 2 x 2 x 5 x 17
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 938, 460, 215, 680
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(938, 460) = 215740
GCD(938, 460) = ( 938 x 460 ) / 215740
= 938 / 460
= 938
Step2:
LCM(2, 215) = 430
GCD(2, 215) = ( 2 x 215 ) / 430
= 2 / 215
= 2
Step3:
LCM(1, 680) = 680
GCD(1, 680) = ( 1 x 680 ) / 680
= 1 / 680
= 1
So, Greatest Common Divisor of 938, 460, 215, 680 is 1
