Given numbers are 231, 343, 199, 619
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(231, 343) = 11319
GCD(231, 343) = ( 231 x 343 ) / 11319
= 231 / 343
= 231
Step2:
LCM(7, 199) = 1393
GCD(7, 199) = ( 7 x 199 ) / 1393
= 7 / 199
= 7
Step3:
LCM(1, 619) = 619
GCD(1, 619) = ( 1 x 619 ) / 619
= 1 / 619
= 1
So, Greatest Common Divisor of 231, 343, 199, 619 is 1
