Answer 1

Answer:

Largest no. divide these is 20

Step-by-step explanation:

623 - 3 = 620

729 - 9 = 720

841 - 1 = 840

Hcf of 620 n 720

720 = 620 × 1 + 100

620 = 100 × 6 + 20

100 = 20 × 5 + 0

Hcf = 20

Largest no. divide these is 20

Answer 2

Answer:

subtract:-

(623-3), (729-9), (841-1)

=620 =720 =840

We have to find H.C.F. here

I'll use continued division method u can use any method

620)720 (1

-620

100)620(6

-600

20)100(5

-100

000

so our last divisor is our H.C.F. = 20

Now the left number 840 will divide by 20

20)840(42

-80

40

-40
