Question

find the HCF by prime factor method: 175,250,300. please give me the answer step by step.​

Answer 1

Answer:

175=5*5*3

250=2*5*5*5

300=2*2*3*5*5

HCF=25

Answer 2

Answer:

25

Step-by-step explanation:

Divide all numbers by 5. This you can guess easily.

You get (175,250,300)/5=(35,50,60)

Again, you can see that they are divisible by 5. So divide it again by 5.

You get 7,10 and 12. Now there is no factor common to all three numbers together.

So you have divided by 5 two times, take 5×5=25. This is HCF.

Or write 175 as 3×5×5

250 as 2×5×5×5

300 as 2×2×3×5×5.

All numbers have 5×5. So 5×5=25 is HCF
