Given numbers are 441, 198, 940, 438
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(441, 198) = 9702
GCD(441, 198) = ( 441 x 198 ) / 9702
= 441 / 198
= 441
Step2:
LCM(9, 940) = 8460
GCD(9, 940) = ( 9 x 940 ) / 8460
= 9 / 940
= 9
Step3:
LCM(1, 438) = 438
GCD(1, 438) = ( 1 x 438 ) / 438
= 1 / 438
= 1
So, Greatest Common Divisor of 441, 198, 940, 438 is 1
