Find the largest number which can exactly divide 513, 783, and 1107.

Correct option is A

Ans. (a)
Sol. We need to find the HCF (Highest Common Factor) of 513, 783, and 1107.
Let’s find the HCF step-by-step:
Step 1: Find HCF of 513 and 783
· 783 ÷ 513 = 1 remainder 270
· 513 ÷ 270 = 1 remainder 243
· 270 ÷ 243 = 1 remainder 27
· 243 ÷ 27 = 9 remainder 0
So, HCF of 513 and 783 = 27
Step 2: Find HCF of 27 and 1107
· 1107 ÷ 27 = 41 remainder 0
So, HCF of all three numbers = 27
