Using Euclids Extended Algorithm:
Calculate x and y in Bézout's Identity
using (15,65)
Bezouts Identity
For 2 numbers a and b and divisor d:
ax + by = d
Extended Algorithm Table
| a math | a | b math | b | d math | d | k math | k |
|---|---|---|---|---|---|---|---|
| Set to 1 | 1 | Set to 0 | 0 | 15 | |||
| Set to 0 | 0 | Set to 1 | 1 | 65 | Quotient of 15/65 | 0 | |
| 1 - (0 x 0) | 1 | 0 - (0 x 1) | 0 | Remainder of 15/65 | 15 | Quotient of 65/15 | 4 |
| 0 - (4 x 1) | -4 | 1 - (4 x 0) | 1 | Remainder of 65/15 | 5 | Quotient of 15/5 | 3 |
| 1 - (3 x -4) | 13 | 0 - (3 x 1) | -3 | Remainder of 15/5 | 0 | Quotient of 5/0 | 0 |
Take the last non-zero row for d:
a = -4 and b = 1
GCD Equation
ax + by = gcd(a,b)
15x + 65y = gcd(15
Final Answer:
GCF(15, 65) = 5
