HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 506, 399 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 506, 399 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 506, 399 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 506, 399 is 1.

HCF(506, 399) = 1

Highest common factor (HCF) of 506, 399 is 1.

Highest Common Factor of 506,399 using Euclid's algorithm

Highest Common Factor of 506,399 is 1

Step 1: Since 506 > 399, we apply the division lemma to 506 and 399, to get

506 = 399 x 1 + 107

Step 2: Since the reminder 399 ≠ 0, we apply division lemma to 107 and 399, to get

399 = 107 x 3 + 78

Step 3: We consider the new divisor 107 and the new remainder 78, and apply the division lemma to get

107 = 78 x 1 + 29

We consider the new divisor 78 and the new remainder 29,and apply the division lemma to get

78 = 29 x 2 + 20

We consider the new divisor 29 and the new remainder 20,and apply the division lemma to get

29 = 20 x 1 + 9

We consider the new divisor 20 and the new remainder 9,and apply the division lemma to get

20 = 9 x 2 + 2

We consider the new divisor 9 and the new remainder 2,and apply the division lemma to get

9 = 2 x 4 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma 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 506 and 399 is 1

Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(20,9) = HCF(29,20) = HCF(78,29) = HCF(107,78) = HCF(399,107) = HCF(506,399) .
