HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 511, 850, 567, 28 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 511, 850, 567, 28 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 511, 850, 567, 28 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 511, 850, 567, 28 is 1.
HCF(511, 850, 567, 28) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 511, 850, 567, 28 is 1.
Step 1: Since 850 > 511, we apply the division lemma to 850 and 511, to get
850 = 511 x 1 + 339
Step 2: Since the reminder 511 ≠ 0, we apply division lemma to 339 and 511, to get
511 = 339 x 1 + 172
Step 3: We consider the new divisor 339 and the new remainder 172, and apply the division lemma to get
339 = 172 x 1 + 167
We consider the new divisor 172 and the new remainder 167,and apply the division lemma to get
172 = 167 x 1 + 5
We consider the new divisor 167 and the new remainder 5,and apply the division lemma to get
167 = 5 x 33 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma 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 511 and 850 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(167,5) = HCF(172,167) = HCF(339,172) = HCF(511,339) = HCF(850,511) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 567 > 1, we apply the division lemma to 567 and 1, to get
567 = 1 x 567 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 567 is 1
Notice that 1 = HCF(567,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 28 > 1, we apply the division lemma to 28 and 1, to get
28 = 1 x 28 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 28 is 1
Notice that 1 = HCF(28,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 511, 850, 567, 28?
Answer: HCF of 511, 850, 567, 28 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 511, 850, 567, 28 using Euclid's Algorithm?
