Question

Find the greatest number that divide 74 170 and 160 leaving a reminder of 10 in each case

Answer 1

Step-by-step explanation:

⇒74-10=64

⇒170-10=160

⇒106-10=96

The greatest number will be the HCF of 64,160,96

• 64=2×2×2×2×2×2
• 160=2×2×2×2×2×5
• 96=2×2×2×2×2×3

>>> Hence the HCF = 2×2×2×2=16

So,the greatest number is 16.
