HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 673, 407, 455 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 673, 407, 455 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 673, 407, 455 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 673, 407, 455 is 1.

HCF(673, 407, 455) = 1

HCF of 673, 407, 455 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 673, 407, 455 is 1.

Highest Common Factor of 673,407,455 using Euclid's algorithm

Highest Common Factor of 673,407,455 is 1

Step 1: Since 673 > 407, we apply the division lemma to 673 and 407, to get

673 = 407 x 1 + 266

Step 2: Since the reminder 407 ≠ 0, we apply division lemma to 266 and 407, to get

407 = 266 x 1 + 141

Step 3: We consider the new divisor 266 and the new remainder 141, and apply the division lemma to get

266 = 141 x 1 + 125

We consider the new divisor 141 and the new remainder 125,and apply the division lemma to get

141 = 125 x 1 + 16

We consider the new divisor 125 and the new remainder 16,and apply the division lemma to get

125 = 16 x 7 + 13

We consider the new divisor 16 and the new remainder 13,and apply the division lemma to get

16 = 13 x 1 + 3

We consider the new divisor 13 and the new remainder 3,and apply the division lemma to get

13 = 3 x 4 + 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 673 and 407 is 1

Notice that 1 = HCF(3,1) = HCF(13,3) = HCF(16,13) = HCF(125,16) = HCF(141,125) = HCF(266,141) = HCF(407,266) = HCF(673,407) .

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

Step 1: Since 455 > 1, we apply the division lemma to 455 and 1, to get

455 = 1 x 455 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 455 is 1

Notice that 1 = HCF(455,1) .
