Question

Number 72 find out the prime factor

Answer 1

Answer:

Step 1: The first step is to divide the number 72 with the smallest prime factor, say 2.

72 ÷ 2 = 36

Step 2: Divide 36 again by 2.

36 ÷ 2 = 18

Step 3: Divide 18 again by 2.

18 ÷ 2 = 9

Step 4: 9 ÷ 2 = 4.5. Now if we divide 9 by 2, we get a fractional number and a factor cannot be a fraction or a decimal number. So, proceed with the next prime factor, say 3.

That is 9 ÷ 3 = 3

Step 5: Similarly, 3 ÷ 3 = 1

Step 6: We cannot proceed further as we have obtained 1 as our quotient.

Step 7: The prime factors of 72 are written as 2 × 2 × 2 × 3 × 3,=  

so 2x2x3

Answer 2

72 is 2 × 2 × 2 × 3 × 3

where 2 and 3 are the prime numbers.
