HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 399, 695, 462 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 399, 695, 462 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 399, 695, 462 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 399, 695, 462 is 1.

HCF(399, 695, 462) = 1

Highest common factor (HCF) of 399, 695, 462 is 1.

Highest Common Factor of 399,695,462 using Euclid's algorithm

Highest Common Factor of 399,695,462 is 1

Step 1: Since 695 > 399, we apply the division lemma to 695 and 399, to get

695 = 399 x 1 + 296

Step 2: Since the reminder 399 ≠ 0, we apply division lemma to 296 and 399, to get

399 = 296 x 1 + 103

Step 3: We consider the new divisor 296 and the new remainder 103, and apply the division lemma to get

296 = 103 x 2 + 90

We consider the new divisor 103 and the new remainder 90,and apply the division lemma to get

103 = 90 x 1 + 13

We consider the new divisor 90 and the new remainder 13,and apply the division lemma to get

90 = 13 x 6 + 12

We consider the new divisor 13 and the new remainder 12,and apply the division lemma to get

13 = 12 x 1 + 1

We consider the new divisor 12 and the new remainder 1,and apply the division lemma to get

12 = 1 x 12 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 399 and 695 is 1

Notice that 1 = HCF(12,1) = HCF(13,12) = HCF(90,13) = HCF(103,90) = HCF(296,103) = HCF(399,296) = HCF(695,399) .

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

Step 1: Since 462 > 1, we apply the division lemma to 462 and 1, to get

462 = 1 x 462 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 462 is 1

Notice that 1 = HCF(462,1) .
