HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 217, 125 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 217, 125 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 217, 125 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 217, 125 is 1.

HCF(217, 125) = 1

Highest common factor (HCF) of 217, 125 is 1.

Highest Common Factor of 217,125 using Euclid's algorithm

Highest Common Factor of 217,125 is 1

Step 1: Since 217 > 125, we apply the division lemma to 217 and 125, to get

217 = 125 x 1 + 92

Step 2: Since the reminder 125 ≠ 0, we apply division lemma to 92 and 125, to get

125 = 92 x 1 + 33

Step 3: We consider the new divisor 92 and the new remainder 33, and apply the division lemma to get

92 = 33 x 2 + 26

We consider the new divisor 33 and the new remainder 26,and apply the division lemma to get

33 = 26 x 1 + 7

We consider the new divisor 26 and the new remainder 7,and apply the division lemma to get

26 = 7 x 3 + 5

We consider the new divisor 7 and the new remainder 5,and apply the division lemma to get

7 = 5 x 1 + 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 217 and 125 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(26,7) = HCF(33,26) = HCF(92,33) = HCF(125,92) = HCF(217,125) .
