To Find :- The unit's digit in the product of 437,

82, 28, 45, and 47.

→ 437 × 82 × 28 × 45 × 47

Since the unit digit of product of n numbers is equal to the unit digit of product of unit digit of every number .

So, taking unit digit of all given numbers we get,

→ 7 × 2 × 8 × 5 × 7

→ 7 × 7 × 8 × 2 × 5

→ 7 × 7 × 8 × (2 × 5)

→ 7 × 7 × 8 × 10

now, when any number is multiplied by 10, unit digit of the product is zero .

therefore,
