Given numbers are 397, 641, 441, 475
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(397, 641) = 254477
GCD(397, 641) = ( 397 x 641 ) / 254477
= 397 / 641
= 397
Step2:
LCM(1, 441) = 441
GCD(1, 441) = ( 1 x 441 ) / 441
= 1 / 441
= 1
Step3:
LCM(1, 475) = 475
GCD(1, 475) = ( 1 x 475 ) / 475
= 1 / 475
= 1
So, Greatest Common Divisor of 397, 641, 441, 475 is 1
