Given numbers are 391, 345, 122, 476
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(391, 345) = 5865
GCD(391, 345) = ( 391 x 345 ) / 5865
= 391 / 345
= 391
Step2:
LCM(23, 122) = 2806
GCD(23, 122) = ( 23 x 122 ) / 2806
= 23 / 122
= 23
Step3:
LCM(1, 476) = 476
GCD(1, 476) = ( 1 x 476 ) / 476
= 1 / 476
= 1
So, Greatest Common Divisor of 391, 345, 122, 476 is 1
