Given numbers are 445, 946, 454, 198
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(445, 946) = 420970
GCD(445, 946) = ( 445 x 946 ) / 420970
= 445 / 946
= 445
Step2:
LCM(1, 454) = 454
GCD(1, 454) = ( 1 x 454 ) / 454
= 1 / 454
= 1
Step3:
LCM(1, 198) = 198
GCD(1, 198) = ( 1 x 198 ) / 198
= 1 / 198
= 1
So, Greatest Common Divisor of 445, 946, 454, 198 is 1
