HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 717, 442 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 717, 442 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 717, 442 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 717, 442 is 1.

HCF(717, 442) = 1

Highest common factor (HCF) of 717, 442 is 1.

Highest Common Factor of 717,442 using Euclid's algorithm

Highest Common Factor of 717,442 is 1

Step 1: Since 717 > 442, we apply the division lemma to 717 and 442, to get

717 = 442 x 1 + 275

Step 2: Since the reminder 442 ≠ 0, we apply division lemma to 275 and 442, to get

442 = 275 x 1 + 167

Step 3: We consider the new divisor 275 and the new remainder 167, and apply the division lemma to get

275 = 167 x 1 + 108

We consider the new divisor 167 and the new remainder 108,and apply the division lemma to get

167 = 108 x 1 + 59

We consider the new divisor 108 and the new remainder 59,and apply the division lemma to get

108 = 59 x 1 + 49

We consider the new divisor 59 and the new remainder 49,and apply the division lemma to get

59 = 49 x 1 + 10

We consider the new divisor 49 and the new remainder 10,and apply the division lemma to get

49 = 10 x 4 + 9

We consider the new divisor 10 and the new remainder 9,and apply the division lemma to get

10 = 9 x 1 + 1

We consider the new divisor 9 and the new remainder 1,and apply the division lemma to get

9 = 1 x 9 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 717 and 442 is 1

Notice that 1 = HCF(9,1) = HCF(10,9) = HCF(49,10) = HCF(59,49) = HCF(108,59) = HCF(167,108) = HCF(275,167) = HCF(442,275) = HCF(717,442) .
