Given Input Data is 90, 98, 55
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 90 is 2 x 3 x 3 x 5
Prime Factorization of 98 is 2 x 7 x 7
Prime Factorization of 55 is 5 x 11

Finding GCD of 90, 98, 55 using LCM Formula
Step1:
Let's calculate the GCD of first two numbers
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(90, 98) = 4410
GCD(90, 98) = ( 90 x 98 ) / 4410
GCD(90, 98) = 8820 / 4410
GCD(90, 98) = 2
Step2:
Here we consider the GCD from the above i.e. 2 as first number and the next as 55
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 55) = 110
GCD(2, 55) = ( 2 x 55 ) / 110
GCD(2, 55) = 110 / 110
GCD(2, 55) = 1
GCD of 90, 98, 55 is 1
