Given numbers are 403, 351, 654, 393
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(403, 351) = 10881
GCD(403, 351) = ( 403 x 351 ) / 10881
= 403 / 351
= 403
Step2:
LCM(13, 654) = 8502
GCD(13, 654) = ( 13 x 654 ) / 8502
= 13 / 654
= 13
Step3:
LCM(1, 393) = 393
GCD(1, 393) = ( 1 x 393 ) / 393
= 1 / 393
= 1
So, Greatest Common Divisor of 403, 351, 654, 393 is 1
