Given numbers are 198, 442, 257, 554
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(198, 442) = 43758
GCD(198, 442) = ( 198 x 442 ) / 43758
= 198 / 442
= 198
Step2:
LCM(2, 257) = 514
GCD(2, 257) = ( 2 x 257 ) / 514
= 2 / 257
= 2
Step3:
LCM(1, 554) = 554
GCD(1, 554) = ( 1 x 554 ) / 554
= 1 / 554
= 1
So, Greatest Common Divisor of 198, 442, 257, 554 is 1
