HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 125, 235 i.e. 5 the largest integer that leaves a remainder zero for all numbers.

HCF of 125, 235 is 5 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 125, 235 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 125, 235 is 5.

HCF(125, 235) = 5

HCF of 125, 235 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 125, 235 is 5.

Highest Common Factor of 125,235 using Euclid's algorithm

Highest Common Factor of 125,235 is 5

Step 1: Since 235 > 125, we apply the division lemma to 235 and 125, to get

235 = 125 x 1 + 110

Step 2: Since the reminder 125 ≠ 0, we apply division lemma to 110 and 125, to get

125 = 110 x 1 + 15

Step 3: We consider the new divisor 110 and the new remainder 15, and apply the division lemma to get

110 = 15 x 7 + 5

We consider the new divisor 15 and the new remainder 5, and apply the division lemma to get

15 = 5 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 125 and 235 is 5

Notice that 5 = HCF(15,5) = HCF(110,15) = HCF(125,110) = HCF(235,125) .
