HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 313, 841, 128 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 313, 841, 128 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 313, 841, 128 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 313, 841, 128 is 1.

HCF(313, 841, 128) = 1

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

HCF of:

Highest common factor (HCF) of 313, 841, 128 is 1.

Highest Common Factor of 313,841,128 using Euclid's algorithm

Highest Common Factor of 313,841,128 is 1

Step 1: Since 841 > 313, we apply the division lemma to 841 and 313, to get

841 = 313 x 2 + 215

Step 2: Since the reminder 313 ≠ 0, we apply division lemma to 215 and 313, to get

313 = 215 x 1 + 98

Step 3: We consider the new divisor 215 and the new remainder 98, and apply the division lemma to get

215 = 98 x 2 + 19

We consider the new divisor 98 and the new remainder 19,and apply the division lemma to get

98 = 19 x 5 + 3

We consider the new divisor 19 and the new remainder 3,and apply the division lemma to get

19 = 3 x 6 + 1

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 313 and 841 is 1

Notice that 1 = HCF(3,1) = HCF(19,3) = HCF(98,19) = HCF(215,98) = HCF(313,215) = HCF(841,313) .

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

Step 1: Since 128 > 1, we apply the division lemma to 128 and 1, to get

128 = 1 x 128 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 128 is 1

Notice that 1 = HCF(128,1) .
