HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 919, 711 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 919, 711 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 919, 711 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 919, 711 is 1.

HCF(919, 711) = 1

Highest common factor (HCF) of 919, 711 is 1.

Highest Common Factor of 919,711 using Euclid's algorithm

Highest Common Factor of 919,711 is 1

Step 1: Since 919 > 711, we apply the division lemma to 919 and 711, to get

919 = 711 x 1 + 208

Step 2: Since the reminder 711 ≠ 0, we apply division lemma to 208 and 711, to get

711 = 208 x 3 + 87

Step 3: We consider the new divisor 208 and the new remainder 87, and apply the division lemma to get

208 = 87 x 2 + 34

We consider the new divisor 87 and the new remainder 34,and apply the division lemma to get

87 = 34 x 2 + 19

We consider the new divisor 34 and the new remainder 19,and apply the division lemma to get

34 = 19 x 1 + 15

We consider the new divisor 19 and the new remainder 15,and apply the division lemma to get

19 = 15 x 1 + 4

We consider the new divisor 15 and the new remainder 4,and apply the division lemma to get

15 = 4 x 3 + 3

We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get

4 = 3 x 1 + 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 919 and 711 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(15,4) = HCF(19,15) = HCF(34,19) = HCF(87,34) = HCF(208,87) = HCF(711,208) = HCF(919,711) .
