HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 596, 68, 487, 254 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 596, 68, 487, 254 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 596, 68, 487, 254 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 596, 68, 487, 254 is 1.
HCF(596, 68, 487, 254) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 596, 68, 487, 254 is 1.
Step 1: Since 596 > 68, we apply the division lemma to 596 and 68, to get
596 = 68 x 8 + 52
Step 2: Since the reminder 68 ≠ 0, we apply division lemma to 52 and 68, to get
68 = 52 x 1 + 16
Step 3: We consider the new divisor 52 and the new remainder 16, and apply the division lemma to get
52 = 16 x 3 + 4
We consider the new divisor 16 and the new remainder 4, and apply the division lemma to get
16 = 4 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 596 and 68 is 4
Notice that 4 = HCF(16,4) = HCF(52,16) = HCF(68,52) = HCF(596,68) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 487 > 4, we apply the division lemma to 487 and 4, to get
487 = 4 x 121 + 3
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 3 and 4, to get
4 = 3 x 1 + 1
Step 3: 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 4 and 487 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(487,4) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 254 > 1, we apply the division lemma to 254 and 1, to get
254 = 1 x 254 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 254 is 1
Notice that 1 = HCF(254,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 596, 68, 487, 254?
Answer: HCF of 596, 68, 487, 254 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 596, 68, 487, 254 using Euclid's Algorithm?
