HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 585, 793, 639 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 585, 793, 639 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 585, 793, 639 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 585, 793, 639 is 1.

HCF(585, 793, 639) = 1

Highest common factor (HCF) of 585, 793, 639 is 1.

Highest Common Factor of 585,793,639 using Euclid's algorithm

Highest Common Factor of 585,793,639 is 1

Step 1: Since 793 > 585, we apply the division lemma to 793 and 585, to get

793 = 585 x 1 + 208

Step 2: Since the reminder 585 ≠ 0, we apply division lemma to 208 and 585, to get

585 = 208 x 2 + 169

Step 3: We consider the new divisor 208 and the new remainder 169, and apply the division lemma to get

208 = 169 x 1 + 39

We consider the new divisor 169 and the new remainder 39,and apply the division lemma to get

169 = 39 x 4 + 13

We consider the new divisor 39 and the new remainder 13,and apply the division lemma to get

39 = 13 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 13, the HCF of 585 and 793 is 13

Notice that 13 = HCF(39,13) = HCF(169,39) = HCF(208,169) = HCF(585,208) = HCF(793,585) .

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

Step 1: Since 639 > 13, we apply the division lemma to 639 and 13, to get

639 = 13 x 49 + 2

Step 2: Since the reminder 13 ≠ 0, we apply division lemma to 2 and 13, to get

13 = 2 x 6 + 1

Step 3: 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 13 and 639 is 1

Notice that 1 = HCF(2,1) = HCF(13,2) = HCF(639,13) .
