HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 395, 646, 955 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 395, 646, 955 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, 646, 955 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, 646, 955 is 1.

HCF(395, 646, 955) = 1

HCF of 395, 646, 955 using Euclid's algorithm

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

HCF of:

Highest common factor (HCF) of 395, 646, 955 is 1.

Highest Common Factor of 395,646,955 using Euclid's algorithm

Highest Common Factor of 395,646,955 is 1

Step 1: Since 646 > 395, we apply the division lemma to 646 and 395, to get

646 = 395 x 1 + 251

Step 2: Since the reminder 395 ≠ 0, we apply division lemma to 251 and 395, to get

395 = 251 x 1 + 144

Step 3: We consider the new divisor 251 and the new remainder 144, and apply the division lemma to get

251 = 144 x 1 + 107

We consider the new divisor 144 and the new remainder 107,and apply the division lemma to get

144 = 107 x 1 + 37

We consider the new divisor 107 and the new remainder 37,and apply the division lemma to get

107 = 37 x 2 + 33

We consider the new divisor 37 and the new remainder 33,and apply the division lemma to get

37 = 33 x 1 + 4

We consider the new divisor 33 and the new remainder 4,and apply the division lemma to get

33 = 4 x 8 + 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 646 is 1

Notice that 1 = HCF(4,1) = HCF(33,4) = HCF(37,33) = HCF(107,37) = HCF(144,107) = HCF(251,144) = HCF(395,251) = HCF(646,395) .

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

Step 1: Since 955 > 1, we apply the division lemma to 955 and 1, to get

955 = 1 x 955 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 955 is 1

Notice that 1 = HCF(955,1) .
