HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 545, 415, 829 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 545, 415, 829 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 545, 415, 829 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 545, 415, 829 is 1.

HCF(545, 415, 829) = 1

HCF of 545, 415, 829 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 545, 415, 829 is 1.

Highest Common Factor of 545,415,829 using Euclid's algorithm

Highest Common Factor of 545,415,829 is 1

Step 1: Since 545 > 415, we apply the division lemma to 545 and 415, to get

545 = 415 x 1 + 130

Step 2: Since the reminder 415 ≠ 0, we apply division lemma to 130 and 415, to get

415 = 130 x 3 + 25

Step 3: We consider the new divisor 130 and the new remainder 25, and apply the division lemma to get

130 = 25 x 5 + 5

We consider the new divisor 25 and the new remainder 5, and apply the division lemma to get

25 = 5 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 545 and 415 is 5

Notice that 5 = HCF(25,5) = HCF(130,25) = HCF(415,130) = HCF(545,415) .

We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 829 > 5, we apply the division lemma to 829 and 5, to get

829 = 5 x 165 + 4

Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 4 and 5, to get

5 = 4 x 1 + 1

Step 3: We consider the new divisor 4 and the new remainder 1, and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 5 and 829 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(829,5) .
