Given numbers are 257, 643, 740, 306
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(257, 643) = 165251
GCD(257, 643) = ( 257 x 643 ) / 165251
= 257 / 643
= 257
Step2:
LCM(1, 740) = 740
GCD(1, 740) = ( 1 x 740 ) / 740
= 1 / 740
= 1
Step3:
LCM(1, 306) = 306
GCD(1, 306) = ( 1 x 306 ) / 306
= 1 / 306
= 1
So, Greatest Common Divisor of 257, 643, 740, 306 is 1
