Two composite numbers are coprime numbers, and their least common multiple is 260 A. 4B. 3C. 1

Two composite numbers are coprime numbers, and their least common multiple is 260 A. 4B. 3C. 1

260 = 2 × 2 × 5 × 13, two numbers are composite numbers and coprime numbers, so 260 = 4 × 65; then there is only one pair of these two numbers, which are 4 and 65, so choose C
