Hope this helps!
Given : Two numbers 30 & 42 is given to us .
To Find : The HCF of 30 & 42 .
Solution : HCF is the highest number which divides the given two or more numbers without leaving any remainder .
So , let's find HCF ( Highest common factor ) by Division method :
= 30 ) 42 ( 1
- 30
__________
12 ) 30 ( 2
- 24
___________
6 ) 12 ( 2
- 12
0 .
The last divisor is 6 .
<u>Hence </u><u>the</u><u> </u><u>HCF</u><u> </u><u>is</u><u> </u><u>6</u><u>.</u>
