Question

If the HCF of 210 and 55 is expressible in the form of 210×5+55y find y

Answer 1

Answer:

-19

Step-by-step explanation:

By Euclid's division algorithm

210 = 55 × 3 + 45

55= 45 × 1 + 10

45= 10 × 4 + 5

10= 5 × 2 + 0

HCF(210,55) = 5

5 = 210 × 5 + 55y

5 - 1050 = 55y

-1045 = 55y

y = -1045/55

y = -19
