HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 942, 855, 814 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 942, 855, 814 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 942, 855, 814 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 942, 855, 814 is 1.
HCF(942, 855, 814) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 942, 855, 814 is 1.
Step 1: Since 942 > 855, we apply the division lemma to 942 and 855, to get
942 = 855 x 1 + 87
Step 2: Since the reminder 855 ≠ 0, we apply division lemma to 87 and 855, to get
855 = 87 x 9 + 72
Step 3: We consider the new divisor 87 and the new remainder 72, and apply the division lemma to get
87 = 72 x 1 + 15
We consider the new divisor 72 and the new remainder 15,and apply the division lemma to get
72 = 15 x 4 + 12
We consider the new divisor 15 and the new remainder 12,and apply the division lemma to get
15 = 12 x 1 + 3
We consider the new divisor 12 and the new remainder 3,and apply the division lemma to get
12 = 3 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 942 and 855 is 3
Notice that 3 = HCF(12,3) = HCF(15,12) = HCF(72,15) = HCF(87,72) = HCF(855,87) = HCF(942,855) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 814 > 3, we apply the division lemma to 814 and 3, to get
814 = 3 x 271 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, 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 3 and 814 is 1
Notice that 1 = HCF(3,1) = HCF(814,3) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 942, 855, 814?
Answer: HCF of 942, 855, 814 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 942, 855, 814 using Euclid's Algorithm?
Answer: For arbitrary numbers 942, 855, 814 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
