HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 717, 905, 445 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 717, 905, 445 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, 905, 445 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, 905, 445 is 1.

HCF(717, 905, 445) = 1

Highest common factor (HCF) of 717, 905, 445 is 1.

Highest Common Factor of 717,905,445 using Euclid's algorithm

Highest Common Factor of 717,905,445 is 1

Step 1: Since 905 > 717, we apply the division lemma to 905 and 717, to get

905 = 717 x 1 + 188

Step 2: Since the reminder 717 ≠ 0, we apply division lemma to 188 and 717, to get

717 = 188 x 3 + 153

Step 3: We consider the new divisor 188 and the new remainder 153, and apply the division lemma to get

188 = 153 x 1 + 35

We consider the new divisor 153 and the new remainder 35,and apply the division lemma to get

153 = 35 x 4 + 13

We consider the new divisor 35 and the new remainder 13,and apply the division lemma to get

35 = 13 x 2 + 9

We consider the new divisor 13 and the new remainder 9,and apply the division lemma to get

13 = 9 x 1 + 4

We consider the new divisor 9 and the new remainder 4,and apply the division lemma to get

9 = 4 x 2 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 717 and 905 is 1

Notice that 1 = HCF(4,1) = HCF(9,4) = HCF(13,9) = HCF(35,13) = HCF(153,35) = HCF(188,153) = HCF(717,188) = HCF(905,717) .

We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 445 > 1, we apply the division lemma to 445 and 1, to get

445 = 1 x 445 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 445 is 1

Notice that 1 = HCF(445,1) .
