HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 431, 606, 630 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 431, 606, 630 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 431, 606, 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 431, 606, 630 is 1.

HCF(431, 606, 630) = 1

Highest common factor (HCF) of 431, 606, 630 is 1.

Highest Common Factor of 431,606,630 using Euclid's algorithm

Highest Common Factor of 431,606,630 is 1

Step 1: Since 606 > 431, we apply the division lemma to 606 and 431, to get

606 = 431 x 1 + 175

Step 2: Since the reminder 431 ≠ 0, we apply division lemma to 175 and 431, to get

431 = 175 x 2 + 81

Step 3: We consider the new divisor 175 and the new remainder 81, and apply the division lemma to get

175 = 81 x 2 + 13

We consider the new divisor 81 and the new remainder 13,and apply the division lemma to get

81 = 13 x 6 + 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 431 and 606 is 1

Notice that 1 = HCF(3,1) = HCF(13,3) = HCF(81,13) = HCF(175,81) = HCF(431,175) = HCF(606,431) .

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

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

630 = 1 x 630 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 630 is 1

Notice that 1 = HCF(630,1) .
