HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 425, 761, 165, 611 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 425, 761, 165, 611 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 425, 761, 165, 611 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 425, 761, 165, 611 is 1.
HCF(425, 761, 165, 611) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 425, 761, 165, 611 is 1.
Step 1: Since 761 > 425, we apply the division lemma to 761 and 425, to get
761 = 425 x 1 + 336
Step 2: Since the reminder 425 ≠ 0, we apply division lemma to 336 and 425, to get
425 = 336 x 1 + 89
Step 3: We consider the new divisor 336 and the new remainder 89, and apply the division lemma to get
336 = 89 x 3 + 69
We consider the new divisor 89 and the new remainder 69,and apply the division lemma to get
89 = 69 x 1 + 20
We consider the new divisor 69 and the new remainder 20,and apply the division lemma to get
69 = 20 x 3 + 9
We consider the new divisor 20 and the new remainder 9,and apply the division lemma to get
20 = 9 x 2 + 2
We consider the new divisor 9 and the new remainder 2,and apply the division lemma to get
9 = 2 x 4 + 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 425 and 761 is 1
Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(20,9) = HCF(69,20) = HCF(89,69) = HCF(336,89) = HCF(425,336) = HCF(761,425) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 165 > 1, we apply the division lemma to 165 and 1, to get
165 = 1 x 165 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 165 is 1
Notice that 1 = HCF(165,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 611 > 1, we apply the division lemma to 611 and 1, to get
611 = 1 x 611 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 611 is 1
Notice that 1 = HCF(611,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 425, 761, 165, 611?
Answer: HCF of 425, 761, 165, 611 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 425, 761, 165, 611 using Euclid's Algorithm?
Answer: For arbitrary numbers 425, 761, 165, 611 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
