HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 307, 417 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 307, 417 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 307, 417 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 307, 417 is 1.

HCF(307, 417) = 1

Highest common factor (HCF) of 307, 417 is 1.

Highest Common Factor of 307,417 using Euclid's algorithm

Highest Common Factor of 307,417 is 1

Step 1: Since 417 > 307, we apply the division lemma to 417 and 307, to get

417 = 307 x 1 + 110

Step 2: Since the reminder 307 ≠ 0, we apply division lemma to 110 and 307, to get

307 = 110 x 2 + 87

Step 3: We consider the new divisor 110 and the new remainder 87, and apply the division lemma to get

110 = 87 x 1 + 23

We consider the new divisor 87 and the new remainder 23,and apply the division lemma to get

87 = 23 x 3 + 18

We consider the new divisor 23 and the new remainder 18,and apply the division lemma to get

23 = 18 x 1 + 5

We consider the new divisor 18 and the new remainder 5,and apply the division lemma to get

18 = 5 x 3 + 3

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

5 = 3 x 1 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 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 307 and 417 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(18,5) = HCF(23,18) = HCF(87,23) = HCF(110,87) = HCF(307,110) = HCF(417,307) .
