HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 551, 775, 695 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 551, 775, 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 551, 775, 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 551, 775, 695 is 1.

HCF(551, 775, 695) = 1

HCF of 551, 775, 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 551, 775, 695 is 1.

Highest Common Factor of 551,775,695 using Euclid's algorithm

Highest Common Factor of 551,775,695 is 1

Step 1: Since 775 > 551, we apply the division lemma to 775 and 551, to get

775 = 551 x 1 + 224

Step 2: Since the reminder 551 ≠ 0, we apply division lemma to 224 and 551, to get

551 = 224 x 2 + 103

Step 3: We consider the new divisor 224 and the new remainder 103, and apply the division lemma to get

224 = 103 x 2 + 18

We consider the new divisor 103 and the new remainder 18,and apply the division lemma to get

103 = 18 x 5 + 13

We consider the new divisor 18 and the new remainder 13,and apply the division lemma to get

18 = 13 x 1 + 5

We consider the new divisor 13 and the new remainder 5,and apply the division lemma to get

13 = 5 x 2 + 3

We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get

5 = 3 x 1 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 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 551 and 775 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(13,5) = HCF(18,13) = HCF(103,18) = HCF(224,103) = HCF(551,224) = HCF(775,551) .

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) .
