Answer 2

2450 can be written as a product of 2 factors in 9 ways.

Given: the number 2450

To find: number of ways to write 2450 as a product of 2 factors

Solution:

To write 2450 as a product of two factors, we first carry out a prime factorisation of 2450

2450 = 1 x 2 x 5 x 5 x 7 x 7

Now, listing the product as two factors, we get

2450 = 1 x 2450

= 2 x 1225

= 5 x 490

= 7 x 350

= 10 x 245

= 14 x 175

= 25 x 98

= 35 x 70

= 49 x 50

⇒ There are 9 ways to write 2450 as a product of 2 factors.
