Given numbers are 308, 638, 17, 554
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(308, 638) = 8932
GCD(308, 638) = ( 308 x 638 ) / 8932
= 308 / 638
= 308
Step2:
LCM(22, 17) = 374
GCD(22, 17) = ( 22 x 17 ) / 374
= 22 / 17
= 22
Step3:
LCM(1, 554) = 554
GCD(1, 554) = ( 1 x 554 ) / 554
= 1 / 554
= 1
So, Greatest Common Divisor of 308, 638, 17, 554 is 1
