HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 885, 782, 689 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 885, 782, 689 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 885, 782, 689 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 885, 782, 689 is 1.
HCF(885, 782, 689) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 885, 782, 689 is 1.
Step 1: Since 885 > 782, we apply the division lemma to 885 and 782, to get
885 = 782 x 1 + 103
Step 2: Since the reminder 782 ≠ 0, we apply division lemma to 103 and 782, to get
782 = 103 x 7 + 61
Step 3: We consider the new divisor 103 and the new remainder 61, and apply the division lemma to get
103 = 61 x 1 + 42
We consider the new divisor 61 and the new remainder 42,and apply the division lemma to get
61 = 42 x 1 + 19
We consider the new divisor 42 and the new remainder 19,and apply the division lemma to get
42 = 19 x 2 + 4
We consider the new divisor 19 and the new remainder 4,and apply the division lemma to get
19 = 4 x 4 + 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 885 and 782 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(19,4) = HCF(42,19) = HCF(61,42) = HCF(103,61) = HCF(782,103) = HCF(885,782) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 689 > 1, we apply the division lemma to 689 and 1, to get
689 = 1 x 689 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 689 is 1
Notice that 1 = HCF(689,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 885, 782, 689?
Answer: HCF of 885, 782, 689 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 885, 782, 689 using Euclid's Algorithm?
Answer: For arbitrary numbers 885, 782, 689 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
