HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 447, 210 i.e. 3 the largest integer that leaves a remainder zero for all numbers.

HCF of 447, 210 is 3 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 447, 210 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 447, 210 is 3.

HCF(447, 210) = 3

HCF of 447, 210 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 447, 210 is 3.

Highest Common Factor of 447,210 using Euclid's algorithm

Highest Common Factor of 447,210 is 3

Step 1: Since 447 > 210, we apply the division lemma to 447 and 210, to get

447 = 210 x 2 + 27

Step 2: Since the reminder 210 ≠ 0, we apply division lemma to 27 and 210, to get

210 = 27 x 7 + 21

Step 3: We consider the new divisor 27 and the new remainder 21, and apply the division lemma to get

27 = 21 x 1 + 6

We consider the new divisor 21 and the new remainder 6,and apply the division lemma to get

21 = 6 x 3 + 3

We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get

6 = 3 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 447 and 210 is 3

Notice that 3 = HCF(6,3) = HCF(21,6) = HCF(27,21) = HCF(210,27) = HCF(447,210) .
