HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 922, 381 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 922, 381 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 922, 381 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 922, 381 is 1.
HCF(922, 381) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 922, 381 is 1.
Step 1: Since 922 > 381, we apply the division lemma to 922 and 381, to get
922 = 381 x 2 + 160
Step 2: Since the reminder 381 ≠ 0, we apply division lemma to 160 and 381, to get
381 = 160 x 2 + 61
Step 3: We consider the new divisor 160 and the new remainder 61, and apply the division lemma to get
160 = 61 x 2 + 38
We consider the new divisor 61 and the new remainder 38,and apply the division lemma to get
61 = 38 x 1 + 23
We consider the new divisor 38 and the new remainder 23,and apply the division lemma to get
38 = 23 x 1 + 15
We consider the new divisor 23 and the new remainder 15,and apply the division lemma to get
23 = 15 x 1 + 8
We consider the new divisor 15 and the new remainder 8,and apply the division lemma to get
15 = 8 x 1 + 7
We consider the new divisor 8 and the new remainder 7,and apply the division lemma to get
8 = 7 x 1 + 1
We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 922 and 381 is 1
Notice that 1 = HCF(7,1) = HCF(8,7) = HCF(15,8) = HCF(23,15) = HCF(38,23) = HCF(61,38) = HCF(160,61) = HCF(381,160) = HCF(922,381) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 922, 381?
Answer: HCF of 922, 381 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 922, 381 using Euclid's Algorithm?
Answer: For arbitrary numbers 922, 381 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
