GIVEN

Numbers- 161 and 207

TO FIND

The HCF and LCM of 161 and 207

SOLUTION

We can simply solve the above problem as follows;

We know that LCM or lowest common factor is the smallest positive integer that can be exactly divisible by given 2 numbers.

We are given 2 numbers - 161 and 207

LCM by long division method-

3 |161, 207

3 |161, 69

3 |161, 23

7 |161, 23

23 |23, 1

1 | 1, 1

LCM of 161 and 207 = 3×3×7×23 =1449

To find the HCF of given numbers we will apply the following formula,

Product of numbers = LCM × HCF

Therefore,

161 × 207 = 1449 × HCF

HCF = 161 × 207/1449 = 23

Hence, The LCM is 1449 and HCF is 23.
