Given numbers are 394, 704, 646, 353
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(394, 704) = 138688
GCD(394, 704) = ( 394 x 704 ) / 138688
= 394 / 704
= 394
Step2:
LCM(2, 646) = 646
GCD(2, 646) = ( 2 x 646 ) / 646
= 2 / 646
= 2
Step3:
LCM(2, 353) = 706
GCD(2, 353) = ( 2 x 353 ) / 706
= 2 / 353
= 2
So, Greatest Common Divisor of 394, 704, 646, 353 is 1
