HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 722, 878 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 722, 878 is 2 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 722, 878 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 722, 878 is 2.
HCF(722, 878) = 2
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 722, 878 is 2.
Step 1: Since 878 > 722, we apply the division lemma to 878 and 722, to get
878 = 722 x 1 + 156
Step 2: Since the reminder 722 ≠ 0, we apply division lemma to 156 and 722, to get
722 = 156 x 4 + 98
Step 3: We consider the new divisor 156 and the new remainder 98, and apply the division lemma to get
156 = 98 x 1 + 58
We consider the new divisor 98 and the new remainder 58,and apply the division lemma to get
98 = 58 x 1 + 40
We consider the new divisor 58 and the new remainder 40,and apply the division lemma to get
58 = 40 x 1 + 18
We consider the new divisor 40 and the new remainder 18,and apply the division lemma to get
40 = 18 x 2 + 4
We consider the new divisor 18 and the new remainder 4,and apply the division lemma to get
18 = 4 x 4 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 722 and 878 is 2
Notice that 2 = HCF(4,2) = HCF(18,4) = HCF(40,18) = HCF(58,40) = HCF(98,58) = HCF(156,98) = HCF(722,156) = HCF(878,722) .
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 722, 878?
Answer: HCF of 722, 878 is 2 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 722, 878 using Euclid's Algorithm?
Answer: For arbitrary numbers 722, 878 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
