HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 885, 689, 781 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 885, 689, 781 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, 689, 781 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, 689, 781 is 1.
HCF(885, 689, 781) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 885, 689, 781 is 1.
Step 1: Since 885 > 689, we apply the division lemma to 885 and 689, to get
885 = 689 x 1 + 196
Step 2: Since the reminder 689 ≠ 0, we apply division lemma to 196 and 689, to get
689 = 196 x 3 + 101
Step 3: We consider the new divisor 196 and the new remainder 101, and apply the division lemma to get
196 = 101 x 1 + 95
We consider the new divisor 101 and the new remainder 95,and apply the division lemma to get
101 = 95 x 1 + 6
We consider the new divisor 95 and the new remainder 6,and apply the division lemma to get
95 = 6 x 15 + 5
We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get
6 = 5 x 1 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 885 and 689 is 1
Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(95,6) = HCF(101,95) = HCF(196,101) = HCF(689,196) = HCF(885,689) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 781 > 1, we apply the division lemma to 781 and 1, to get
781 = 1 x 781 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 781 is 1
Notice that 1 = HCF(781,1) .
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, 689, 781?
Answer: HCF of 885, 689, 781 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 885, 689, 781 using Euclid's Algorithm?
Answer: For arbitrary numbers 885, 689, 781 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
