HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 364, 685, 775 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 364, 685, 775 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 364, 685, 775 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 364, 685, 775 is 1.

HCF(364, 685, 775) = 1

HCF of 364, 685, 775 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 364, 685, 775 is 1.

Highest Common Factor of 364,685,775 using Euclid's algorithm

Highest Common Factor of 364,685,775 is 1

Step 1: Since 685 > 364, we apply the division lemma to 685 and 364, to get

685 = 364 x 1 + 321

Step 2: Since the reminder 364 ≠ 0, we apply division lemma to 321 and 364, to get

364 = 321 x 1 + 43

Step 3: We consider the new divisor 321 and the new remainder 43, and apply the division lemma to get

321 = 43 x 7 + 20

We consider the new divisor 43 and the new remainder 20,and apply the division lemma to get

43 = 20 x 2 + 3

We consider the new divisor 20 and the new remainder 3,and apply the division lemma to get

20 = 3 x 6 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 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 364 and 685 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(20,3) = HCF(43,20) = HCF(321,43) = HCF(364,321) = HCF(685,364) .

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

Step 1: Since 775 > 1, we apply the division lemma to 775 and 1, to get

775 = 1 x 775 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 775 is 1

Notice that 1 = HCF(775,1) .
