HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 708, 538, 379, 80 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 708, 538, 379, 80 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 708, 538, 379, 80 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 708, 538, 379, 80 is 1.
HCF(708, 538, 379, 80) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 708, 538, 379, 80 is 1.
Step 1: Since 708 > 538, we apply the division lemma to 708 and 538, to get
708 = 538 x 1 + 170
Step 2: Since the reminder 538 ≠ 0, we apply division lemma to 170 and 538, to get
538 = 170 x 3 + 28
Step 3: We consider the new divisor 170 and the new remainder 28, and apply the division lemma to get
170 = 28 x 6 + 2
We consider the new divisor 28 and the new remainder 2, and apply the division lemma to get
28 = 2 x 14 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 708 and 538 is 2
Notice that 2 = HCF(28,2) = HCF(170,28) = HCF(538,170) = HCF(708,538) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 379 > 2, we apply the division lemma to 379 and 2, to get
379 = 2 x 189 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 2 and 379 is 1
Notice that 1 = HCF(2,1) = HCF(379,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 80 > 1, we apply the division lemma to 80 and 1, to get
80 = 1 x 80 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 80 is 1
Notice that 1 = HCF(80,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 708, 538, 379, 80?
Answer: HCF of 708, 538, 379, 80 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 708, 538, 379, 80 using Euclid's Algorithm?
