Solve 1-b, 2-d, 3-a, 4-c

Calculate

1 - b, 2 - d, 3 - a, 4 - c

Write the terms one above the other

1 - b 2 - d 3 - a 4 - c

Write the prime factorization of 1 - b

1 - b = 1 - b 2 - d 3 - a 4 - c

Write the prime factorization of 2 - d

1 - b = 1 - b 2 - d = 2 - d 3 - a 4 - c

Write the prime factorization of 3 - a

1 - b = 1 - b 2 - d = 2 - d 3 - a = 3 - a 4 - c

Write the prime factorization of 4 - c

1 - b = 1 - b 2 - d = 2 - d 3 - a = 3 - a 4 - c = 4 - c

Solution

(1 - b) (2 - d) (3 - a) (4 - c)
