HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 126, 856, 480 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 126, 856, 480 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 126, 856, 480 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 126, 856, 480 is 2.
HCF(126, 856, 480) = 2
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 126, 856, 480 is 2.
Step 1: Since 856 > 126, we apply the division lemma to 856 and 126, to get
856 = 126 x 6 + 100
Step 2: Since the reminder 126 ≠ 0, we apply division lemma to 100 and 126, to get
126 = 100 x 1 + 26
Step 3: We consider the new divisor 100 and the new remainder 26, and apply the division lemma to get
100 = 26 x 3 + 22
We consider the new divisor 26 and the new remainder 22,and apply the division lemma to get
26 = 22 x 1 + 4
We consider the new divisor 22 and the new remainder 4,and apply the division lemma to get
22 = 4 x 5 + 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 126 and 856 is 2
Notice that 2 = HCF(4,2) = HCF(22,4) = HCF(26,22) = HCF(100,26) = HCF(126,100) = HCF(856,126) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 480 > 2, we apply the division lemma to 480 and 2, to get
480 = 2 x 240 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 480 is 2
Notice that 2 = HCF(480,2) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 126, 856, 480?
Answer: HCF of 126, 856, 480 is 2 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 126, 856, 480 using Euclid's Algorithm?
Answer: For arbitrary numbers 126, 856, 480 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
