HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 310, 455, 794 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 310, 455, 794 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 310, 455, 794 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 310, 455, 794 is 1.

HCF(310, 455, 794) = 1

HCF of 310, 455, 794 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 310, 455, 794 is 1.

Highest Common Factor of 310,455,794 using Euclid's algorithm

Highest Common Factor of 310,455,794 is 1

Step 1: Since 455 > 310, we apply the division lemma to 455 and 310, to get

455 = 310 x 1 + 145

Step 2: Since the reminder 310 ≠ 0, we apply division lemma to 145 and 310, to get

310 = 145 x 2 + 20

Step 3: We consider the new divisor 145 and the new remainder 20, and apply the division lemma to get

145 = 20 x 7 + 5

We consider the new divisor 20 and the new remainder 5, and apply the division lemma to get

20 = 5 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 310 and 455 is 5

Notice that 5 = HCF(20,5) = HCF(145,20) = HCF(310,145) = HCF(455,310) .

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

Step 1: Since 794 > 5, we apply the division lemma to 794 and 5, to get

794 = 5 x 158 + 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 794 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(794,5) .
