HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 247, 417 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 247, 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 247, 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 247, 417 is 1.

HCF(247, 417) = 1

Highest common factor (HCF) of 247, 417 is 1.

Highest Common Factor of 247,417 using Euclid's algorithm

Highest Common Factor of 247,417 is 1

Step 1: Since 417 > 247, we apply the division lemma to 417 and 247, to get

417 = 247 x 1 + 170

Step 2: Since the reminder 247 ≠ 0, we apply division lemma to 170 and 247, to get

247 = 170 x 1 + 77

Step 3: We consider the new divisor 170 and the new remainder 77, and apply the division lemma to get

170 = 77 x 2 + 16

We consider the new divisor 77 and the new remainder 16,and apply the division lemma to get

77 = 16 x 4 + 13

We consider the new divisor 16 and the new remainder 13,and apply the division lemma to get

16 = 13 x 1 + 3

We consider the new divisor 13 and the new remainder 3,and apply the division lemma to get

13 = 3 x 4 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 247 and 417 is 1

Notice that 1 = HCF(3,1) = HCF(13,3) = HCF(16,13) = HCF(77,16) = HCF(170,77) = HCF(247,170) = HCF(417,247) .
