HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 680, 818, 476, 76 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 680, 818, 476, 76 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 680, 818, 476, 76 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 680, 818, 476, 76 is 2.
HCF(680, 818, 476, 76) = 2
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 680, 818, 476, 76 is 2.
Step 1: Since 818 > 680, we apply the division lemma to 818 and 680, to get
818 = 680 x 1 + 138
Step 2: Since the reminder 680 ≠ 0, we apply division lemma to 138 and 680, to get
680 = 138 x 4 + 128
Step 3: We consider the new divisor 138 and the new remainder 128, and apply the division lemma to get
138 = 128 x 1 + 10
We consider the new divisor 128 and the new remainder 10,and apply the division lemma to get
128 = 10 x 12 + 8
We consider the new divisor 10 and the new remainder 8,and apply the division lemma to get
10 = 8 x 1 + 2
We consider the new divisor 8 and the new remainder 2,and apply the division lemma to get
8 = 2 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 680 and 818 is 2
Notice that 2 = HCF(8,2) = HCF(10,8) = HCF(128,10) = HCF(138,128) = HCF(680,138) = HCF(818,680) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 476 > 2, we apply the division lemma to 476 and 2, to get
476 = 2 x 238 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 476 is 2
Notice that 2 = HCF(476,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 76 > 2, we apply the division lemma to 76 and 2, to get
76 = 2 x 38 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 76 is 2
Notice that 2 = HCF(76,2) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 680, 818, 476, 76?
Answer: HCF of 680, 818, 476, 76 is 2 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 680, 818, 476, 76 using Euclid's Algorithm?
