HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 460, 1970, 6473 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 460, 1970, 6473 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 460, 1970, 6473 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 460, 1970, 6473 is 1.

HCF(460, 1970, 6473) = 1

Highest common factor (HCF) of 460, 1970, 6473 is 1.

Highest Common Factor of 460,1970,6473 using Euclid's algorithm

Highest Common Factor of 460,1970,6473 is 1

Step 1: Since 1970 > 460, we apply the division lemma to 1970 and 460, to get

1970 = 460 x 4 + 130

Step 2: Since the reminder 460 ≠ 0, we apply division lemma to 130 and 460, to get

460 = 130 x 3 + 70

Step 3: We consider the new divisor 130 and the new remainder 70, and apply the division lemma to get

130 = 70 x 1 + 60

We consider the new divisor 70 and the new remainder 60,and apply the division lemma to get

70 = 60 x 1 + 10

We consider the new divisor 60 and the new remainder 10,and apply the division lemma to get

60 = 10 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 10, the HCF of 460 and 1970 is 10

Notice that 10 = HCF(60,10) = HCF(70,60) = HCF(130,70) = HCF(460,130) = HCF(1970,460) .

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

Step 1: Since 6473 > 10, we apply the division lemma to 6473 and 10, to get

6473 = 10 x 647 + 3

Step 2: Since the reminder 10 ≠ 0, we apply division lemma to 3 and 10, to get

10 = 3 x 3 + 1

Step 3: 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 10 and 6473 is 1

Notice that 1 = HCF(3,1) = HCF(10,3) = HCF(6473,10) .
