HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 485, 659, 576 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 485, 659, 576 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 485, 659, 576 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 485, 659, 576 is 1.
HCF(485, 659, 576) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 485, 659, 576 is 1.
Step 1: Since 659 > 485, we apply the division lemma to 659 and 485, to get
659 = 485 x 1 + 174
Step 2: Since the reminder 485 ≠ 0, we apply division lemma to 174 and 485, to get
485 = 174 x 2 + 137
Step 3: We consider the new divisor 174 and the new remainder 137, and apply the division lemma to get
174 = 137 x 1 + 37
We consider the new divisor 137 and the new remainder 37,and apply the division lemma to get
137 = 37 x 3 + 26
We consider the new divisor 37 and the new remainder 26,and apply the division lemma to get
37 = 26 x 1 + 11
We consider the new divisor 26 and the new remainder 11,and apply the division lemma to get
26 = 11 x 2 + 4
We consider the new divisor 11 and the new remainder 4,and apply the division lemma to get
11 = 4 x 2 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 485 and 659 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(11,4) = HCF(26,11) = HCF(37,26) = HCF(137,37) = HCF(174,137) = HCF(485,174) = HCF(659,485) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 576 > 1, we apply the division lemma to 576 and 1, to get
576 = 1 x 576 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 576 is 1
Notice that 1 = HCF(576,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 485, 659, 576?
Answer: HCF of 485, 659, 576 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 485, 659, 576 using Euclid's Algorithm?
Answer: For arbitrary numbers 485, 659, 576 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
