HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 501, 942, 423 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 501, 942, 423 is 3 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 501, 942, 423 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 501, 942, 423 is 3.
HCF(501, 942, 423) = 3
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 501, 942, 423 is 3.
Step 1: Since 942 > 501, we apply the division lemma to 942 and 501, to get
942 = 501 x 1 + 441
Step 2: Since the reminder 501 ≠ 0, we apply division lemma to 441 and 501, to get
501 = 441 x 1 + 60
Step 3: We consider the new divisor 441 and the new remainder 60, and apply the division lemma to get
441 = 60 x 7 + 21
We consider the new divisor 60 and the new remainder 21,and apply the division lemma to get
60 = 21 x 2 + 18
We consider the new divisor 21 and the new remainder 18,and apply the division lemma to get
21 = 18 x 1 + 3
We consider the new divisor 18 and the new remainder 3,and apply the division lemma to get
18 = 3 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 501 and 942 is 3
Notice that 3 = HCF(18,3) = HCF(21,18) = HCF(60,21) = HCF(441,60) = HCF(501,441) = HCF(942,501) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 423 > 3, we apply the division lemma to 423 and 3, to get
423 = 3 x 141 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 423 is 3
Notice that 3 = HCF(423,3) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 501, 942, 423?
Answer: HCF of 501, 942, 423 is 3 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 501, 942, 423 using Euclid's Algorithm?
Answer: For arbitrary numbers 501, 942, 423 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
