Given numbers are 397, 257, 612, 295
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(397, 257) = 102029
GCD(397, 257) = ( 397 x 257 ) / 102029
= 397 / 257
= 397
Step2:
LCM(1, 612) = 612
GCD(1, 612) = ( 1 x 612 ) / 612
= 1 / 612
= 1
Step3:
LCM(1, 295) = 295
GCD(1, 295) = ( 1 x 295 ) / 295
= 1 / 295
= 1
So, Greatest Common Divisor of 397, 257, 612, 295 is 1
