HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 896, 464, 21 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 896, 464, 21 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 896, 464, 21 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 896, 464, 21 is 1.

HCF(896, 464, 21) = 1

HCF of 896, 464, 21 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 896, 464, 21 is 1.

Highest Common Factor of 896,464,21 using Euclid's algorithm

Highest Common Factor of 896,464,21 is 1

Step 1: Since 896 > 464, we apply the division lemma to 896 and 464, to get

896 = 464 x 1 + 432

Step 2: Since the reminder 464 ≠ 0, we apply division lemma to 432 and 464, to get

464 = 432 x 1 + 32

Step 3: We consider the new divisor 432 and the new remainder 32, and apply the division lemma to get

432 = 32 x 13 + 16

We consider the new divisor 32 and the new remainder 16, and apply the division lemma to get

32 = 16 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 16, the HCF of 896 and 464 is 16

Notice that 16 = HCF(32,16) = HCF(432,32) = HCF(464,432) = HCF(896,464) .


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

Step 1: Since 21 > 16, we apply the division lemma to 21 and 16, to get

21 = 16 x 1 + 5

Step 2: Since the reminder 16 ≠ 0, we apply division lemma to 5 and 16, to get

16 = 5 x 3 + 1

Step 3: We consider the new divisor 5 and the new remainder 1, and apply the division lemma to get

5 = 1 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 16 and 21 is 1

Notice that 1 = HCF(5,1) = HCF(16,5) = HCF(21,16) .
