HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 646, 896, 338 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 646, 896, 338 is 2 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 646, 896, 338 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 646, 896, 338 is 2.

HCF(646, 896, 338) = 2

HCF of 646, 896, 338 using Euclid's algorithm

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

Highest common factor (HCF) of 646, 896, 338 is 2.

Highest Common Factor of 646,896,338 using Euclid's algorithm

Highest Common Factor of 646,896,338 is 2

Step 1: Since 896 > 646, we apply the division lemma to 896 and 646, to get

896 = 646 x 1 + 250

Step 2: Since the reminder 646 ≠ 0, we apply division lemma to 250 and 646, to get

646 = 250 x 2 + 146

Step 3: We consider the new divisor 250 and the new remainder 146, and apply the division lemma to get

250 = 146 x 1 + 104

We consider the new divisor 146 and the new remainder 104,and apply the division lemma to get

146 = 104 x 1 + 42

We consider the new divisor 104 and the new remainder 42,and apply the division lemma to get

104 = 42 x 2 + 20

We consider the new divisor 42 and the new remainder 20,and apply the division lemma to get

42 = 20 x 2 + 2

We consider the new divisor 20 and the new remainder 2,and apply the division lemma to get

20 = 2 x 10 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 646 and 896 is 2

Notice that 2 = HCF(20,2) = HCF(42,20) = HCF(104,42) = HCF(146,104) = HCF(250,146) = HCF(646,250) = HCF(896,646) .


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

Step 1: Since 338 > 2, we apply the division lemma to 338 and 2, to get

338 = 2 x 169 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 338 is 2

Notice that 2 = HCF(338,2) .
