Ответ:

1) 15 и 77, 2) 15 и 16, 3) 16 и 21, 4) 16 и 77

Пошаговое объяснение:

Взаимно простыми числами будут те пары чисел, у которых нет никаких других общих делителей кроме ±1.

Разложим данные числа на простые множители:

15 = 5 × 3

16 = 2 × 2 × 2 × 2

21 = 7 × 3

77 = 7 × 11

Получим следующие пары: 15 и 77, 15 и 16, 16 и 21, 16 и 77. Других пар мы составить не сможем.

Если все понятно, то отмечай ответ как лучший :)
