HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 965, 678, 497 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 965, 678, 497 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 965, 678, 497 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 965, 678, 497 is 1.

HCF(965, 678, 497) = 1

HCF of 965, 678, 497 using Euclid's algorithm

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

Highest common factor (HCF) of 965, 678, 497 is 1.

Highest Common Factor of 965,678,497 using Euclid's algorithm

Highest Common Factor of 965,678,497 is 1

Step 1: Since 965 > 678, we apply the division lemma to 965 and 678, to get

965 = 678 x 1 + 287

Step 2: Since the reminder 678 ≠ 0, we apply division lemma to 287 and 678, to get

678 = 287 x 2 + 104

Step 3: We consider the new divisor 287 and the new remainder 104, and apply the division lemma to get

287 = 104 x 2 + 79

We consider the new divisor 104 and the new remainder 79,and apply the division lemma to get

104 = 79 x 1 + 25

We consider the new divisor 79 and the new remainder 25,and apply the division lemma to get

79 = 25 x 3 + 4

We consider the new divisor 25 and the new remainder 4,and apply the division lemma to get

25 = 4 x 6 + 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 965 and 678 is 1

Notice that 1 = HCF(4,1) = HCF(25,4) = HCF(79,25) = HCF(104,79) = HCF(287,104) = HCF(678,287) = HCF(965,678) .

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

Step 1: Since 497 > 1, we apply the division lemma to 497 and 1, to get

497 = 1 x 497 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 497 is 1

Notice that 1 = HCF(497,1) .
