Given numbers are 342, 756, 393, 619
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(342, 756) = 14364
GCD(342, 756) = ( 342 x 756 ) / 14364
= 342 / 756
= 342
Step2:
LCM(18, 393) = 2358
GCD(18, 393) = ( 18 x 393 ) / 2358
= 18 / 393
= 18
Step3:
LCM(3, 619) = 1857
GCD(3, 619) = ( 3 x 619 ) / 1857
= 3 / 619
= 3
So, Greatest Common Divisor of 342, 756, 393, 619 is 1
