Given numbers are 397, 367, 644, 803
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(397, 367) = 145699
GCD(397, 367) = ( 397 x 367 ) / 145699
= 397 / 367
= 397
Step2:
LCM(1, 644) = 644
GCD(1, 644) = ( 1 x 644 ) / 644
= 1 / 644
= 1
Step3:
LCM(1, 803) = 803
GCD(1, 803) = ( 1 x 803 ) / 803
= 1 / 803
= 1
So, Greatest Common Divisor of 397, 367, 644, 803 is 1
