HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 845, 316, 320 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 845, 316, 320 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 845, 316, 320 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 845, 316, 320 is 1.

HCF(845, 316, 320) = 1

HCF of 845, 316, 320 using Euclid's algorithm

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

Highest common factor (HCF) of 845, 316, 320 is 1.

Highest Common Factor of 845,316,320 using Euclid's algorithm

Highest Common Factor of 845,316,320 is 1

Step 1: Since 845 > 316, we apply the division lemma to 845 and 316, to get

845 = 316 x 2 + 213

Step 2: Since the reminder 316 ≠ 0, we apply division lemma to 213 and 316, to get

316 = 213 x 1 + 103

Step 3: We consider the new divisor 213 and the new remainder 103, and apply the division lemma to get

213 = 103 x 2 + 7

We consider the new divisor 103 and the new remainder 7,and apply the division lemma to get

103 = 7 x 14 + 5

We consider the new divisor 7 and the new remainder 5,and apply the division lemma to get

7 = 5 x 1 + 2

We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get

5 = 2 x 2 + 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 845 and 316 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(103,7) = HCF(213,103) = HCF(316,213) = HCF(845,316) .

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

Step 1: Since 320 > 1, we apply the division lemma to 320 and 1, to get

320 = 1 x 320 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 320 is 1

Notice that 1 = HCF(320,1) .
