Given numbers are 645, 938, 403, 441
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(645, 938) = 605010
GCD(645, 938) = ( 645 x 938 ) / 605010
= 645 / 938
= 645
Step2:
LCM(1, 403) = 403
GCD(1, 403) = ( 1 x 403 ) / 403
= 1 / 403
= 1
Step3:
LCM(1, 441) = 441
GCD(1, 441) = ( 1 x 441 ) / 441
= 1 / 441
= 1
So, Greatest Common Divisor of 645, 938, 403, 441 is 1
