HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 670, 490, 630 i.e. 10 the largest integer that leaves a remainder zero for all numbers.

HCF of 670, 490, 630 is 10 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 670, 490, 630 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 670, 490, 630 is 10.

HCF(670, 490, 630) = 10

HCF of 670, 490, 630 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

Highest Common Factor of 670,490,630 using Euclid's algorithm

Highest Common Factor of 670,490,630 is 10

Step 1: Since 670 > 490, we apply the division lemma to 670 and 490, to get

670 = 490 x 1 + 180

Step 2: Since the reminder 490 ≠ 0, we apply division lemma to 180 and 490, to get

490 = 180 x 2 + 130

Step 3: We consider the new divisor 180 and the new remainder 130, and apply the division lemma to get

180 = 130 x 1 + 50

We consider the new divisor 130 and the new remainder 50,and apply the division lemma to get

130 = 50 x 2 + 30

We consider the new divisor 50 and the new remainder 30,and apply the division lemma to get

50 = 30 x 1 + 20

We consider the new divisor 30 and the new remainder 20,and apply the division lemma to get

30 = 20 x 1 + 10

We consider the new divisor 20 and the new remainder 10,and apply the division lemma to get

20 = 10 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 10, the HCF of 670 and 490 is 10

Notice that 10 = HCF(20,10) = HCF(30,20) = HCF(50,30) = HCF(130,50) = HCF(180,130) = HCF(490,180) = HCF(670,490) .

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

Step 1: Since 630 > 10, we apply the division lemma to 630 and 10, to get

630 = 10 x 63 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 10, the HCF of 10 and 630 is 10

Notice that 10 = HCF(630,10) .
