HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 655, 969 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 655, 969 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, 969 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, 969 is 1.

HCF(655, 969) = 1

Highest common factor (HCF) of 655, 969 is 1.

Highest Common Factor of 655,969 using Euclid's algorithm

Highest Common Factor of 655,969 is 1

Step 1: Since 969 > 655, we apply the division lemma to 969 and 655, to get

969 = 655 x 1 + 314

Step 2: Since the reminder 655 ≠ 0, we apply division lemma to 314 and 655, to get

655 = 314 x 2 + 27

Step 3: We consider the new divisor 314 and the new remainder 27, and apply the division lemma to get

314 = 27 x 11 + 17

We consider the new divisor 27 and the new remainder 17,and apply the division lemma to get

27 = 17 x 1 + 10

We consider the new divisor 17 and the new remainder 10,and apply the division lemma to get

17 = 10 x 1 + 7

We consider the new divisor 10 and the new remainder 7,and apply the division lemma to get

10 = 7 x 1 + 3

We consider the new divisor 7 and the new remainder 3,and apply the division lemma to get

7 = 3 x 2 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 655 and 969 is 1

Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(10,7) = HCF(17,10) = HCF(27,17) = HCF(314,27) = HCF(655,314) = HCF(969,655) .
