GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(397, 690) = 273930
GCD(397, 690) = ( 397 x 690 ) / 273930
= 397 / 690
= 397
Step2:
LCM(1, 256) = 256
GCD(1, 256) = ( 1 x 256 ) / 256
= 1 / 256
= 1
Step3:
LCM(1, 918) = 918
GCD(1, 918) = ( 1 x 918 ) / 918
= 1 / 918
= 1
So, Greatest Common Divisor of 397, 690, 256, 918 is 1
