HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 396, 953, 308 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 396, 953, 308 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 396, 953, 308 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 396, 953, 308 is 1.

HCF(396, 953, 308) = 1

HCF of 396, 953, 308 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 396, 953, 308 is 1.

Highest Common Factor of 396,953,308 using Euclid's algorithm

Highest Common Factor of 396,953,308 is 1

Step 1: Since 953 > 396, we apply the division lemma to 953 and 396, to get

953 = 396 x 2 + 161

Step 2: Since the reminder 396 ≠ 0, we apply division lemma to 161 and 396, to get

396 = 161 x 2 + 74

Step 3: We consider the new divisor 161 and the new remainder 74, and apply the division lemma to get

161 = 74 x 2 + 13

We consider the new divisor 74 and the new remainder 13,and apply the division lemma to get

74 = 13 x 5 + 9

We consider the new divisor 13 and the new remainder 9,and apply the division lemma to get

13 = 9 x 1 + 4

We consider the new divisor 9 and the new remainder 4,and apply the division lemma to get

9 = 4 x 2 + 1

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 396 and 953 is 1

Notice that 1 = HCF(4,1) = HCF(9,4) = HCF(13,9) = HCF(74,13) = HCF(161,74) = HCF(396,161) = HCF(953,396) .

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

Step 1: Since 308 > 1, we apply the division lemma to 308 and 1, to get

308 = 1 x 308 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 308 is 1

Notice that 1 = HCF(308,1) .
