HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 562, 765, 971 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 562, 765, 971 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 562, 765, 971 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 562, 765, 971 is 1.

HCF(562, 765, 971) = 1

HCF of 562, 765, 971 using Euclid's algorithm

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

Highest common factor (HCF) of 562, 765, 971 is 1.

Highest Common Factor of 562,765,971 using Euclid's algorithm

Highest Common Factor of 562,765,971 is 1

Step 1: Since 765 > 562, we apply the division lemma to 765 and 562, to get

765 = 562 x 1 + 203

Step 2: Since the reminder 562 ≠ 0, we apply division lemma to 203 and 562, to get

562 = 203 x 2 + 156

Step 3: We consider the new divisor 203 and the new remainder 156, and apply the division lemma to get

203 = 156 x 1 + 47

We consider the new divisor 156 and the new remainder 47,and apply the division lemma to get

156 = 47 x 3 + 15

We consider the new divisor 47 and the new remainder 15,and apply the division lemma to get

47 = 15 x 3 + 2

We consider the new divisor 15 and the new remainder 2,and apply the division lemma to get

15 = 2 x 7 + 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 562 and 765 is 1

Notice that 1 = HCF(2,1) = HCF(15,2) = HCF(47,15) = HCF(156,47) = HCF(203,156) = HCF(562,203) = HCF(765,562) .

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

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

971 = 1 x 971 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 971 is 1

Notice that 1 = HCF(971,1) .
