HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 464, 845 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 464, 845 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 464, 845 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 464, 845 is 1.

HCF(464, 845) = 1

Highest common factor (HCF) of 464, 845 is 1.

Highest Common Factor of 464,845 using Euclid's algorithm

Highest Common Factor of 464,845 is 1

Step 1: Since 845 > 464, we apply the division lemma to 845 and 464, to get

845 = 464 x 1 + 381

Step 2: Since the reminder 464 ≠ 0, we apply division lemma to 381 and 464, to get

464 = 381 x 1 + 83

Step 3: We consider the new divisor 381 and the new remainder 83, and apply the division lemma to get

381 = 83 x 4 + 49

We consider the new divisor 83 and the new remainder 49,and apply the division lemma to get

83 = 49 x 1 + 34

We consider the new divisor 49 and the new remainder 34,and apply the division lemma to get

49 = 34 x 1 + 15

We consider the new divisor 34 and the new remainder 15,and apply the division lemma to get

34 = 15 x 2 + 4

We consider the new divisor 15 and the new remainder 4,and apply the division lemma to get

15 = 4 x 3 + 3

We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get

4 = 3 x 1 + 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 464 and 845 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(15,4) = HCF(34,15) = HCF(49,34) = HCF(83,49) = HCF(381,83) = HCF(464,381) = HCF(845,464) .
