Prime factors of 305 are 5 x 61
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 157, 720, 694, 305
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(157, 720) = 113040
GCD(157, 720) = ( 157 x 720 ) / 113040
= 157 / 720
= 157
Step2:
LCM(1, 694) = 694
GCD(1, 694) = ( 1 x 694 ) / 694
= 1 / 694
= 1
Step3:
LCM(1, 305) = 305
GCD(1, 305) = ( 1 x 305 ) / 305
= 1 / 305
= 1
So, Greatest Common Divisor of 157, 720, 694, 305 is 1
