GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(454, 208) = 47216
GCD(454, 208) = ( 454 x 208 ) / 47216
= 454 / 208
= 454
Step2:
LCM(2, 399) = 798
GCD(2, 399) = ( 2 x 399 ) / 798
= 2 / 399
= 2
Step3:
LCM(1, 198) = 198
GCD(1, 198) = ( 1 x 198 ) / 198
= 1 / 198
= 1
So, Greatest Common Divisor of 454, 208, 399, 198 is 1
