HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 710, 256, 140 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 710, 256, 140 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 710, 256, 140 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 710, 256, 140 is 2.
HCF(710, 256, 140) = 2
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 710, 256, 140 is 2.
Step 1: Since 710 > 256, we apply the division lemma to 710 and 256, to get
710 = 256 x 2 + 198
Step 2: Since the reminder 256 ≠ 0, we apply division lemma to 198 and 256, to get
256 = 198 x 1 + 58
Step 3: We consider the new divisor 198 and the new remainder 58, and apply the division lemma to get
198 = 58 x 3 + 24
We consider the new divisor 58 and the new remainder 24,and apply the division lemma to get
58 = 24 x 2 + 10
We consider the new divisor 24 and the new remainder 10,and apply the division lemma to get
24 = 10 x 2 + 4
We consider the new divisor 10 and the new remainder 4,and apply the division lemma to get
10 = 4 x 2 + 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 710 and 256 is 2
Notice that 2 = HCF(4,2) = HCF(10,4) = HCF(24,10) = HCF(58,24) = HCF(198,58) = HCF(256,198) = HCF(710,256) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 140 > 2, we apply the division lemma to 140 and 2, to get
140 = 2 x 70 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 140 is 2
Notice that 2 = HCF(140,2) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 710, 256, 140?
Answer: HCF of 710, 256, 140 is 2 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 710, 256, 140 using Euclid's Algorithm?
Answer: For arbitrary numbers 710, 256, 140 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
