HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 665, 943, 673 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 665, 943, 673 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 665, 943, 673 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 665, 943, 673 is 1.

HCF(665, 943, 673) = 1

HCF of 665, 943, 673 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 665, 943, 673 is 1.

Highest Common Factor of 665,943,673 using Euclid's algorithm

Highest Common Factor of 665,943,673 is 1

Step 1: Since 943 > 665, we apply the division lemma to 943 and 665, to get

943 = 665 x 1 + 278

Step 2: Since the reminder 665 ≠ 0, we apply division lemma to 278 and 665, to get

665 = 278 x 2 + 109

Step 3: We consider the new divisor 278 and the new remainder 109, and apply the division lemma to get

278 = 109 x 2 + 60

We consider the new divisor 109 and the new remainder 60,and apply the division lemma to get

109 = 60 x 1 + 49

We consider the new divisor 60 and the new remainder 49,and apply the division lemma to get

60 = 49 x 1 + 11

We consider the new divisor 49 and the new remainder 11,and apply the division lemma to get

49 = 11 x 4 + 5

We consider the new divisor 11 and the new remainder 5,and apply the division lemma to get

11 = 5 x 2 + 1

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 665 and 943 is 1

Notice that 1 = HCF(5,1) = HCF(11,5) = HCF(49,11) = HCF(60,49) = HCF(109,60) = HCF(278,109) = HCF(665,278) = HCF(943,665) .

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

Step 1: Since 673 > 1, we apply the division lemma to 673 and 1, to get

673 = 1 x 673 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 673 is 1

Notice that 1 = HCF(673,1) .
