HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 458, 670, 673 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 458, 670, 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 458, 670, 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 458, 670, 673 is 1.

HCF(458, 670, 673) = 1

HCF of 458, 670, 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 458, 670, 673 is 1.

Highest Common Factor of 458,670,673 using Euclid's algorithm

Highest Common Factor of 458,670,673 is 1

Step 1: Since 670 > 458, we apply the division lemma to 670 and 458, to get

670 = 458 x 1 + 212

Step 2: Since the reminder 458 ≠ 0, we apply division lemma to 212 and 458, to get

458 = 212 x 2 + 34

Step 3: We consider the new divisor 212 and the new remainder 34, and apply the division lemma to get

212 = 34 x 6 + 8

We consider the new divisor 34 and the new remainder 8,and apply the division lemma to get

34 = 8 x 4 + 2

We consider the new divisor 8 and the new remainder 2,and apply the division lemma to get

8 = 2 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 458 and 670 is 2

Notice that 2 = HCF(8,2) = HCF(34,8) = HCF(212,34) = HCF(458,212) = HCF(670,458) .

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

Step 1: Since 673 > 2, we apply the division lemma to 673 and 2, to get

673 = 2 x 336 + 1

Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 2 and 673 is 1

Notice that 1 = HCF(2,1) = HCF(673,2) .
