GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(454, 298) = 67646
GCD(454, 298) = ( 454 x 298 ) / 67646
= 454 / 298
= 454
Step2:
LCM(2, 214) = 214
GCD(2, 214) = ( 2 x 214 ) / 214
= 2 / 214
= 2
Step3:
LCM(2, 817) = 1634
GCD(2, 817) = ( 2 x 817 ) / 1634
= 2 / 817
= 2
So, Greatest Common Divisor of 454, 298, 214, 817 is 1
