HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 275, 172, 239 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 275, 172, 239 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 275, 172, 239 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 275, 172, 239 is 1.

HCF(275, 172, 239) = 1

HCF of 275, 172, 239 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 275, 172, 239 is 1.

Highest Common Factor of 275,172,239 using Euclid's algorithm

Highest Common Factor of 275,172,239 is 1

Step 1: Since 275 > 172, we apply the division lemma to 275 and 172, to get

275 = 172 x 1 + 103

Step 2: Since the reminder 172 ≠ 0, we apply division lemma to 103 and 172, to get

172 = 103 x 1 + 69

Step 3: We consider the new divisor 103 and the new remainder 69, and apply the division lemma to get

103 = 69 x 1 + 34

We consider the new divisor 69 and the new remainder 34,and apply the division lemma to get

69 = 34 x 2 + 1

We consider the new divisor 34 and the new remainder 1,and apply the division lemma to get

34 = 1 x 34 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 275 and 172 is 1

Notice that 1 = HCF(34,1) = HCF(69,34) = HCF(103,69) = HCF(172,103) = HCF(275,172) .


We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 239 > 1, we apply the division lemma to 239 and 1, to get

239 = 1 x 239 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 239 is 1

Notice that 1 = HCF(239,1) .
