HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 455, 275, 674 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 455, 275, 674 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 455, 275, 674 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 455, 275, 674 is 1.

HCF(455, 275, 674) = 1

Highest common factor (HCF) of 455, 275, 674 is 1.

Highest Common Factor of 455,275,674 using Euclid's algorithm

Highest Common Factor of 455,275,674 is 1

Step 1: Since 455 > 275, we apply the division lemma to 455 and 275, to get

455 = 275 x 1 + 180

Step 2: Since the reminder 275 ≠ 0, we apply division lemma to 180 and 275, to get

275 = 180 x 1 + 95

Step 3: We consider the new divisor 180 and the new remainder 95, and apply the division lemma to get

180 = 95 x 1 + 85

We consider the new divisor 95 and the new remainder 85,and apply the division lemma to get

95 = 85 x 1 + 10

We consider the new divisor 85 and the new remainder 10,and apply the division lemma to get

85 = 10 x 8 + 5

We consider the new divisor 10 and the new remainder 5,and apply the division lemma to get

10 = 5 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 455 and 275 is 5

Notice that 5 = HCF(10,5) = HCF(85,10) = HCF(95,85) = HCF(180,95) = HCF(275,180) = HCF(455,275) .

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

Step 1: Since 674 > 5, we apply the division lemma to 674 and 5, to get

674 = 5 x 134 + 4

Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 4 and 5, to get

5 = 4 x 1 + 1

Step 3: We consider the new divisor 4 and the new remainder 1, and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 5 and 674 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(674,5) .
