Given numbers are 394, 578, 391, 154
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(394, 578) = 113866
GCD(394, 578) = ( 394 x 578 ) / 113866
= 394 / 578
= 394
Step2:
LCM(2, 391) = 782
GCD(2, 391) = ( 2 x 391 ) / 782
= 2 / 391
= 2
Step3:
LCM(1, 154) = 154
GCD(1, 154) = ( 1 x 154 ) / 154
= 1 / 154
= 1
So, Greatest Common Divisor of 394, 578, 391, 154 is 1
