Answer 2

The common factor of 10abc, 30ab, 50bc is 10b (option 3).

Given,

The three terms: 10abc, 30ab, 50bc.

To find,

The common factor.

Solution,

We can easily solve this problem by following the given steps.

According to the question,

We have the following three terms:

10abc, 30ab, 50bc

Now, first, we will find the prime factors of the given terms. (Prime numbers can only be divided by 1 and themselves. For example, 2,3, and 7 are prime numbers.)

10abc = 2×5×a×b×c

30ab = 2×5×3×a×b

50bc = 2×5×5×b×c

So, the common factor of the three terms is:

2×5×b

10b

Hence, the common factor of 10abc, 30ab, 50bc is 10b.
