HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 828, 165 i.e. 3 the largest integer that leaves a remainder zero for all numbers.

HCF of 828, 165 is 3 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 828, 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 828, 165 is 3.

HCF(828, 165) = 3

HCF of 828, 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 828, 165 is 3.

Highest Common Factor of 828,165 using Euclid's algorithm

Highest Common Factor of 828,165 is 3

Step 1: Since 828 > 165, we apply the division lemma to 828 and 165, to get

828 = 165 x 5 + 3

Step 2: Since the reminder 165 ≠ 0, we apply division lemma to 3 and 165, to get

165 = 3 x 55 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 828 and 165 is 3

Notice that 3 = HCF(165,3) = HCF(828,165) .
