HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 801, 976, 61 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 801, 976, 61 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 801, 976, 61 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 801, 976, 61 is 1.
HCF(801, 976, 61) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 801, 976, 61 is 1.
Step 1: Since 976 > 801, we apply the division lemma to 976 and 801, to get
976 = 801 x 1 + 175
Step 2: Since the reminder 801 ≠ 0, we apply division lemma to 175 and 801, to get
801 = 175 x 4 + 101
Step 3: We consider the new divisor 175 and the new remainder 101, and apply the division lemma to get
175 = 101 x 1 + 74
We consider the new divisor 101 and the new remainder 74,and apply the division lemma to get
101 = 74 x 1 + 27
We consider the new divisor 74 and the new remainder 27,and apply the division lemma to get
74 = 27 x 2 + 20
We consider the new divisor 27 and the new remainder 20,and apply the division lemma to get
27 = 20 x 1 + 7
We consider the new divisor 20 and the new remainder 7,and apply the division lemma to get
20 = 7 x 2 + 6
We consider the new divisor 7 and the new remainder 6,and apply the division lemma to get
7 = 6 x 1 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 801 and 976 is 1
Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(20,7) = HCF(27,20) = HCF(74,27) = HCF(101,74) = HCF(175,101) = HCF(801,175) = HCF(976,801) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 61 > 1, we apply the division lemma to 61 and 1, to get
61 = 1 x 61 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 61 is 1
Notice that 1 = HCF(61,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
Answer: Euclid's Division Algorithm is a technique to compute the Highest Common Factor (HCF) of given positive integers.
2. what is the HCF of 801, 976, 61?
Answer: HCF of 801, 976, 61 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 801, 976, 61 using Euclid's Algorithm?
Answer: For arbitrary numbers 801, 976, 61 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
