HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 655, 971, 229 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 655, 971, 229 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 655, 971, 229 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 655, 971, 229 is 1.

HCF(655, 971, 229) = 1

HCF of 655, 971, 229 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 655, 971, 229 is 1.

Highest Common Factor of 655,971,229 using Euclid's algorithm

Highest Common Factor of 655,971,229 is 1

Step 1: Since 971 > 655, we apply the division lemma to 971 and 655, to get

971 = 655 x 1 + 316

Step 2: Since the reminder 655 ≠ 0, we apply division lemma to 316 and 655, to get

655 = 316 x 2 + 23

Step 3: We consider the new divisor 316 and the new remainder 23, and apply the division lemma to get

316 = 23 x 13 + 17

We consider the new divisor 23 and the new remainder 17,and apply the division lemma to get

23 = 17 x 1 + 6

We consider the new divisor 17 and the new remainder 6,and apply the division lemma to get

17 = 6 x 2 + 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 655 and 971 is 1

Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(17,6) = HCF(23,17) = HCF(316,23) = HCF(655,316) = HCF(971,655) .

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

Step 1: Since 229 > 1, we apply the division lemma to 229 and 1, to get

229 = 1 x 229 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 229 is 1

Notice that 1 = HCF(229,1) .
