Given numbers are 394, 906, 388, 619
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(394, 906) = 178482
GCD(394, 906) = ( 394 x 906 ) / 178482
= 394 / 906
= 394
Step2:
LCM(2, 388) = 388
GCD(2, 388) = ( 2 x 388 ) / 388
= 2 / 388
= 2
Step3:
LCM(2, 619) = 1238
GCD(2, 619) = ( 2 x 619 ) / 1238
= 2 / 619
= 2
So, Greatest Common Divisor of 394, 906, 388, 619 is 1
