Given numbers are 297, 483, 390, 355
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(297, 483) = 47817
GCD(297, 483) = ( 297 x 483 ) / 47817
= 297 / 483
= 297
Step2:
LCM(3, 390) = 390
GCD(3, 390) = ( 3 x 390 ) / 390
= 3 / 390
= 3
Step3:
LCM(3, 355) = 1065
GCD(3, 355) = ( 3 x 355 ) / 1065
= 3 / 355
= 3
So, Greatest Common Divisor of 297, 483, 390, 355 is 1
