Given numbers are 297, 278, 145, 230
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(297, 278) = 82566
GCD(297, 278) = ( 297 x 278 ) / 82566
= 297 / 278
= 297
Step2:
LCM(1, 145) = 145
GCD(1, 145) = ( 1 x 145 ) / 145
= 1 / 145
= 1
Step3:
LCM(1, 230) = 230
GCD(1, 230) = ( 1 x 230 ) / 230
= 1 / 230
= 1
So, Greatest Common Divisor of 297, 278, 145, 230 is 1
