HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 139, 805, 63 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 139, 805, 63 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 139, 805, 63 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 139, 805, 63 is 1.

HCF(139, 805, 63) = 1

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 139, 805, 63 is 1.

Highest Common Factor of 139,805,63 using Euclid's algorithm

Highest Common Factor of 139,805,63 is 1

Step 1: Since 805 > 139, we apply the division lemma to 805 and 139, to get

805 = 139 x 5 + 110

Step 2: Since the reminder 139 ≠ 0, we apply division lemma to 110 and 139, to get

139 = 110 x 1 + 29

Step 3: We consider the new divisor 110 and the new remainder 29, and apply the division lemma to get

110 = 29 x 3 + 23

We consider the new divisor 29 and the new remainder 23,and apply the division lemma to get

29 = 23 x 1 + 6

We consider the new divisor 23 and the new remainder 6,and apply the division lemma to get

23 = 6 x 3 + 5

We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get

6 = 5 x 1 + 1

We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get

5 = 1 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 139 and 805 is 1

Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(23,6) = HCF(29,23) = HCF(110,29) = HCF(139,110) = HCF(805,139) .


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

Step 1: Since 63 > 1, we apply the division lemma to 63 and 1, to get

63 = 1 x 63 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 63 is 1

Notice that 1 = HCF(63,1) .
