HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 133, 165 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 133, 165 is 1 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.

Consider we have numbers 133, 165 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b

Highest common factor (HCF) of 133, 165 is 1.

HCF(133, 165) = 1

HCF of 133, 165 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 133, 165 is 1.

Highest Common Factor of 133,165 using Euclid's algorithm

Highest Common Factor of 133,165 is 1

Step 1: Since 165 > 133, we apply the division lemma to 165 and 133, to get

165 = 133 x 1 + 32

Step 2: Since the reminder 133 ≠ 0, we apply division lemma to 32 and 133, to get

133 = 32 x 4 + 5

Step 3: We consider the new divisor 32 and the new remainder 5, and apply the division lemma to get

32 = 5 x 6 + 2

We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get

5 = 2 x 2 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 133 and 165 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(32,5) = HCF(133,32) = HCF(165,133) .
