HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 395, 964, 656 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 395, 964, 656 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 395, 964, 656 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 395, 964, 656 is 1.

HCF(395, 964, 656) = 1

Highest common factor (HCF) of 395, 964, 656 is 1.

Highest Common Factor of 395,964,656 using Euclid's algorithm

Highest Common Factor of 395,964,656 is 1

Step 1: Since 964 > 395, we apply the division lemma to 964 and 395, to get

964 = 395 x 2 + 174

Step 2: Since the reminder 395 ≠ 0, we apply division lemma to 174 and 395, to get

395 = 174 x 2 + 47

Step 3: We consider the new divisor 174 and the new remainder 47, and apply the division lemma to get

174 = 47 x 3 + 33

We consider the new divisor 47 and the new remainder 33,and apply the division lemma to get

47 = 33 x 1 + 14

We consider the new divisor 33 and the new remainder 14,and apply the division lemma to get

33 = 14 x 2 + 5

We consider the new divisor 14 and the new remainder 5,and apply the division lemma to get

14 = 5 x 2 + 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 395 and 964 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(14,5) = HCF(33,14) = HCF(47,33) = HCF(174,47) = HCF(395,174) = HCF(964,395) .

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

Step 1: Since 656 > 1, we apply the division lemma to 656 and 1, to get

656 = 1 x 656 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 656 is 1

Notice that 1 = HCF(656,1) .
