HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 553, 194, 695 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 553, 194, 695 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 553, 194, 695 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 553, 194, 695 is 1.

HCF(553, 194, 695) = 1

HCF of 553, 194, 695 using Euclid's algorithm

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

HCF of:

Highest common factor (HCF) of 553, 194, 695 is 1.

Highest Common Factor of 553,194,695 using Euclid's algorithm

Highest Common Factor of 553,194,695 is 1

Step 1: Since 553 > 194, we apply the division lemma to 553 and 194, to get

553 = 194 x 2 + 165

Step 2: Since the reminder 194 ≠ 0, we apply division lemma to 165 and 194, to get

194 = 165 x 1 + 29

Step 3: We consider the new divisor 165 and the new remainder 29, and apply the division lemma to get

165 = 29 x 5 + 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 553 and 194 is 1

Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(20,9) = HCF(29,20) = HCF(165,29) = HCF(194,165) = HCF(553,194) .

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

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

695 = 1 x 695 + 0

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

Notice that 1 = HCF(695,1) .
