Now I’ll write a few things about the number 1202:
- 1202 is a composite number.
- Prime factorization: 1202 = 2 × 601
- The exponents in the prime factorization are 1 and 1. Adding one to each and multiplying we get (1 + 1)(1 + 1) = 2 × 2 = 4. Therefore 1202 has exactly 4 factors.
- Factors of 1202: 1, 2, 601, 1202
- Factor pairs: 1202 = 1 × 1202 or 2 × 601
- 1202 has no square factors that allow its square root to be simplified. √1202 ≈ 34.66987
29² + 19² = 1202
1202 is the hypotenuse of a Pythagorean triple:
480-1102-1202 calculated from 29² – 19², 2(29)(19), 29² + 19²
2(24² + 5²) = 2(601) = 1202 so that Pythagorean triple can also be calculated from
2(2)(24)(5), 2(24² – 5²), 2(24² + 5²)
Try out both ways to get the triple!
