HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 955, 255, 331 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 955, 255, 331 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 955, 255, 331 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 955, 255, 331 is 1.

HCF(955, 255, 331) = 1

HCF of 955, 255, 331 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 955, 255, 331 is 1.

Highest Common Factor of 955,255,331 using Euclid's algorithm

Highest Common Factor of 955,255,331 is 1

Step 1: Since 955 > 255, we apply the division lemma to 955 and 255, to get

955 = 255 x 3 + 190

Step 2: Since the reminder 255 ≠ 0, we apply division lemma to 190 and 255, to get

255 = 190 x 1 + 65

Step 3: We consider the new divisor 190 and the new remainder 65, and apply the division lemma to get

190 = 65 x 2 + 60

We consider the new divisor 65 and the new remainder 60,and apply the division lemma to get

65 = 60 x 1 + 5

We consider the new divisor 60 and the new remainder 5,and apply the division lemma to get

60 = 5 x 12 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 955 and 255 is 5

Notice that 5 = HCF(60,5) = HCF(65,60) = HCF(190,65) = HCF(255,190) = HCF(955,255) .

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

Step 1: Since 331 > 5, we apply the division lemma to 331 and 5, to get

331 = 5 x 66 + 1

Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 1 and 5, to get

5 = 1 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 5 and 331 is 1

Notice that 1 = HCF(5,1) = HCF(331,5) .
