HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 442, 651 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 442, 651 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 442, 651 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 442, 651 is 1.

HCF(442, 651) = 1

HCF of 442, 651 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 442, 651 is 1.

Highest Common Factor of 442,651 using Euclid's algorithm

Highest Common Factor of 442,651 is 1

Step 1: Since 651 > 442, we apply the division lemma to 651 and 442, to get

651 = 442 x 1 + 209

Step 2: Since the reminder 442 ≠ 0, we apply division lemma to 209 and 442, to get

442 = 209 x 2 + 24

Step 3: We consider the new divisor 209 and the new remainder 24, and apply the division lemma to get

209 = 24 x 8 + 17

We consider the new divisor 24 and the new remainder 17,and apply the division lemma to get

24 = 17 x 1 + 7

We consider the new divisor 17 and the new remainder 7,and apply the division lemma to get

17 = 7 x 2 + 3

We consider the new divisor 7 and the new remainder 3,and apply the division lemma to get

7 = 3 x 2 + 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 442 and 651 is 1

Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(17,7) = HCF(24,17) = HCF(209,24) = HCF(442,209) = HCF(651,442) .
