HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 688, 447, 958 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 688, 447, 958 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 688, 447, 958 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 688, 447, 958 is 1.

HCF(688, 447, 958) = 1

HCF of 688, 447, 958 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 688, 447, 958 is 1.

Highest Common Factor of 688,447,958 using Euclid's algorithm

Highest Common Factor of 688,447,958 is 1

Step 1: Since 688 > 447, we apply the division lemma to 688 and 447, to get

688 = 447 x 1 + 241

Step 2: Since the reminder 447 ≠ 0, we apply division lemma to 241 and 447, to get

447 = 241 x 1 + 206

Step 3: We consider the new divisor 241 and the new remainder 206, and apply the division lemma to get

241 = 206 x 1 + 35

We consider the new divisor 206 and the new remainder 35,and apply the division lemma to get

206 = 35 x 5 + 31

We consider the new divisor 35 and the new remainder 31,and apply the division lemma to get

35 = 31 x 1 + 4

We consider the new divisor 31 and the new remainder 4,and apply the division lemma to get

31 = 4 x 7 + 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 688 and 447 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(31,4) = HCF(35,31) = HCF(206,35) = HCF(241,206) = HCF(447,241) = HCF(688,447) .

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

Step 1: Since 958 > 1, we apply the division lemma to 958 and 1, to get

958 = 1 x 958 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 958 is 1

Notice that 1 = HCF(958,1) .
