Prime factors of 115 are 5 x 23
Prime factors of 461 are 461
Prime factors of 649 are 11 x 59
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 770, 115, 461, 649
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(770, 115) = 17710
GCD(770, 115) = ( 770 x 115 ) / 17710
= 770 / 115
= 770
Step2:
LCM(5, 461) = 2305
GCD(5, 461) = ( 5 x 461 ) / 2305
= 5 / 461
= 5
Step3:
LCM(1, 649) = 649
GCD(1, 649) = ( 1 x 649 ) / 649
= 1 / 649
= 1
So, Greatest Common Divisor of 770, 115, 461, 649 is 1
