HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 919, 685 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 919, 685 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, 685 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, 685 is 1.

HCF(919, 685) = 1

Highest common factor (HCF) of 919, 685 is 1.

Highest Common Factor of 919,685 using Euclid's algorithm

Highest Common Factor of 919,685 is 1

Step 1: Since 919 > 685, we apply the division lemma to 919 and 685, to get

919 = 685 x 1 + 234

Step 2: Since the reminder 685 ≠ 0, we apply division lemma to 234 and 685, to get

685 = 234 x 2 + 217

Step 3: We consider the new divisor 234 and the new remainder 217, and apply the division lemma to get

234 = 217 x 1 + 17

We consider the new divisor 217 and the new remainder 17,and apply the division lemma to get

217 = 17 x 12 + 13

We consider the new divisor 17 and the new remainder 13,and apply the division lemma to get

17 = 13 x 1 + 4

We consider the new divisor 13 and the new remainder 4,and apply the division lemma to get

13 = 4 x 3 + 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 919 and 685 is 1

Notice that 1 = HCF(4,1) = HCF(13,4) = HCF(17,13) = HCF(217,17) = HCF(234,217) = HCF(685,234) = HCF(919,685) .
