HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 975, 613, 685 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 975, 613, 685 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 975, 613, 685 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 975, 613, 685 is 1.

HCF(975, 613, 685) = 1

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

HCF of:

Highest common factor (HCF) of 975, 613, 685 is 1.

Highest Common Factor of 975,613,685 using Euclid's algorithm

Highest Common Factor of 975,613,685 is 1

Step 1: Since 975 > 613, we apply the division lemma to 975 and 613, to get

975 = 613 x 1 + 362

Step 2: Since the reminder 613 ≠ 0, we apply division lemma to 362 and 613, to get

613 = 362 x 1 + 251

Step 3: We consider the new divisor 362 and the new remainder 251, and apply the division lemma to get

362 = 251 x 1 + 111

We consider the new divisor 251 and the new remainder 111,and apply the division lemma to get

251 = 111 x 2 + 29

We consider the new divisor 111 and the new remainder 29,and apply the division lemma to get

111 = 29 x 3 + 24

We consider the new divisor 29 and the new remainder 24,and apply the division lemma to get

29 = 24 x 1 + 5

We consider the new divisor 24 and the new remainder 5,and apply the division lemma to get

24 = 5 x 4 + 4

We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get

5 = 4 x 1 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 975 and 613 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(24,5) = HCF(29,24) = HCF(111,29) = HCF(251,111) = HCF(362,251) = HCF(613,362) = HCF(975,613) .

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

Step 1: Since 685 > 1, we apply the division lemma to 685 and 1, to get

685 = 1 x 685 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 685 is 1

Notice that 1 = HCF(685,1) .
