Question

find the hcf and lcm of 161 and 207​

Answer 1

Answer:

Here is the answer:

Step-by-step explanation:

1. 161=7*23.

207=3*3*23

=3^2*23

As LCM = Product of lowest power of each common factor.

So LCM(161,207)=3*3*7*23

=161*9

=1449

2. As HCF*LCM=Product of the two numbers.

So HCF*1449=161*207

=33327

So HCF=33327/1449

=23.

So the HCF(161,207) is 23 and LCM(161,207) is 1449.
