HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 858, 1229 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 858, 1229 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 858, 1229 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 858, 1229 is 1.
HCF(858, 1229) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 858, 1229 is 1.
Step 1: Since 1229 > 858, we apply the division lemma to 1229 and 858, to get
1229 = 858 x 1 + 371
Step 2: Since the reminder 858 ≠ 0, we apply division lemma to 371 and 858, to get
858 = 371 x 2 + 116
Step 3: We consider the new divisor 371 and the new remainder 116, and apply the division lemma to get
371 = 116 x 3 + 23
We consider the new divisor 116 and the new remainder 23,and apply the division lemma to get
116 = 23 x 5 + 1
We consider the new divisor 23 and the new remainder 1,and apply the division lemma to get
23 = 1 x 23 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 858 and 1229 is 1
Notice that 1 = HCF(23,1) = HCF(116,23) = HCF(371,116) = HCF(858,371) = HCF(1229,858) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 858, 1229?
Answer: HCF of 858, 1229 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 858, 1229 using Euclid's Algorithm?
Answer: For arbitrary numbers 858, 1229 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
