Given numbers are 361, 646, 353, 547
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(361, 646) = 12274
GCD(361, 646) = ( 361 x 646 ) / 12274
= 361 / 646
= 361
Step2:
LCM(19, 353) = 6707
GCD(19, 353) = ( 19 x 353 ) / 6707
= 19 / 353
= 19
Step3:
LCM(1, 547) = 547
GCD(1, 547) = ( 1 x 547 ) / 547
= 1 / 547
= 1
So, Greatest Common Divisor of 361, 646, 353, 547 is 1
