HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 661, 824, 968 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 661, 824, 968 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 661, 824, 968 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 661, 824, 968 is 1.
HCF(661, 824, 968) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 661, 824, 968 is 1.
Step 1: Since 824 > 661, we apply the division lemma to 824 and 661, to get
824 = 661 x 1 + 163
Step 2: Since the reminder 661 ≠ 0, we apply division lemma to 163 and 661, to get
661 = 163 x 4 + 9
Step 3: We consider the new divisor 163 and the new remainder 9, and apply the division lemma to get
163 = 9 x 18 + 1
We consider the new divisor 9 and the new remainder 1, and apply the division lemma to get
9 = 1 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 661 and 824 is 1
Notice that 1 = HCF(9,1) = HCF(163,9) = HCF(661,163) = HCF(824,661) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 968 > 1, we apply the division lemma to 968 and 1, to get
968 = 1 x 968 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 968 is 1
Notice that 1 = HCF(968,1) .
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 661, 824, 968?
Answer: HCF of 661, 824, 968 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 661, 824, 968 using Euclid's Algorithm?
Answer: For arbitrary numbers 661, 824, 968 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
