HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 437, 717 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 437, 717 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 437, 717 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 437, 717 is 1.

HCF(437, 717) = 1

Highest common factor (HCF) of 437, 717 is 1.

Highest Common Factor of 437,717 using Euclid's algorithm

Highest Common Factor of 437,717 is 1

Step 1: Since 717 > 437, we apply the division lemma to 717 and 437, to get

717 = 437 x 1 + 280

Step 2: Since the reminder 437 ≠ 0, we apply division lemma to 280 and 437, to get

437 = 280 x 1 + 157

Step 3: We consider the new divisor 280 and the new remainder 157, and apply the division lemma to get

280 = 157 x 1 + 123

We consider the new divisor 157 and the new remainder 123,and apply the division lemma to get

157 = 123 x 1 + 34

We consider the new divisor 123 and the new remainder 34,and apply the division lemma to get

123 = 34 x 3 + 21

We consider the new divisor 34 and the new remainder 21,and apply the division lemma to get

34 = 21 x 1 + 13

We consider the new divisor 21 and the new remainder 13,and apply the division lemma to get

21 = 13 x 1 + 8

We consider the new divisor 13 and the new remainder 8,and apply the division lemma to get

13 = 8 x 1 + 5

We consider the new divisor 8 and the new remainder 5,and apply the division lemma to get

8 = 5 x 1 + 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 437 and 717 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(13,8) = HCF(21,13) = HCF(34,21) = HCF(123,34) = HCF(157,123) = HCF(280,157) = HCF(437,280) = HCF(717,437) .
