Question

find the greatest number which will divide 148 and 249 to leave reminder 8 and 18 respectively​

Answer 1

Answer:

u do yourself time give me example

Step-by-step explanation:

Remainder in case of 148 = 4 Number = 148 - 4 =

144

Remainder in case of 246 = 6

Number = 246 6 = 240 Remainder in case of 623 = 11

Number = 623 - 11 = 612 Now, we have find the H.C.F. of 144. 240 and 612 2 1 144, 240, 612 2 1 72, 120, 306 3 36, 60, 153 | 12, 20, 51

and 612 2 | 144, 240, 612 21 72, 120, 306 3 | 36, 60, 153 | 12, 20, 51 H.C.F. of 144, 240 and 612 = 2*2*3 = 12

Therefore, the required number is 12 that will divide 148, 246 and 623 leaving remainders 4, 6 and 11 respectively.

Answer 2

Answer:

7

Step-by-step explanation:

To find that number, we will subtract the remainder and then divide by the least divisor... and then find it's HCF!

=>(i) (148 - 8)/2 = 140/2 = 70

(ii) (249-18)/3 = 231/3 = 77         (Why 3? Because the lowest divisor is 3 and

                                                 not  2 here)

Here, the greatest common factor is 7, therefore the Number is 7!

I hope you get it!
