Prime factors of 261 are 3 x 3 x 29
Prime factors of 409 are 409
Prime factors of 777 are 3 x 7 x 37
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 120, 261, 409, 777
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(120, 261) = 10440
GCD(120, 261) = ( 120 x 261 ) / 10440
= 120 / 261
= 120
Step2:
LCM(3, 409) = 1227
GCD(3, 409) = ( 3 x 409 ) / 1227
= 3 / 409
= 3
Step3:
LCM(1, 777) = 777
GCD(1, 777) = ( 1 x 777 ) / 777
= 1 / 777
= 1
So, Greatest Common Divisor of 120, 261, 409, 777 is 1
