HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 556, 168, 719 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 556, 168, 719 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 556, 168, 719 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 556, 168, 719 is 1.
HCF(556, 168, 719) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 556, 168, 719 is 1.
Step 1: Since 556 > 168, we apply the division lemma to 556 and 168, to get
556 = 168 x 3 + 52
Step 2: Since the reminder 168 ≠ 0, we apply division lemma to 52 and 168, to get
168 = 52 x 3 + 12
Step 3: We consider the new divisor 52 and the new remainder 12, and apply the division lemma to get
52 = 12 x 4 + 4
We consider the new divisor 12 and the new remainder 4, and apply the division lemma to get
12 = 4 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 556 and 168 is 4
Notice that 4 = HCF(12,4) = HCF(52,12) = HCF(168,52) = HCF(556,168) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 719 > 4, we apply the division lemma to 719 and 4, to get
719 = 4 x 179 + 3
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 3 and 4, to get
4 = 3 x 1 + 1
Step 3: We consider the new divisor 3 and the new remainder 1, and apply the division lemma 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 4 and 719 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(719,4) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 556, 168, 719?
Answer: HCF of 556, 168, 719 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 556, 168, 719 using Euclid's Algorithm?
Answer: For arbitrary numbers 556, 168, 719 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
