HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 844, 255, 970 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 844, 255, 970 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 844, 255, 970 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 844, 255, 970 is 1.

HCF(844, 255, 970) = 1

HCF of 844, 255, 970 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 844, 255, 970 is 1.

Highest Common Factor of 844,255,970 using Euclid's algorithm

Highest Common Factor of 844,255,970 is 1

Step 1: Since 844 > 255, we apply the division lemma to 844 and 255, to get

844 = 255 x 3 + 79

Step 2: Since the reminder 255 ≠ 0, we apply division lemma to 79 and 255, to get

255 = 79 x 3 + 18

Step 3: We consider the new divisor 79 and the new remainder 18, and apply the division lemma to get

79 = 18 x 4 + 7

We consider the new divisor 18 and the new remainder 7,and apply the division lemma to get

18 = 7 x 2 + 4

We consider the new divisor 7 and the new remainder 4,and apply the division lemma to get

7 = 4 x 1 + 3

We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get

4 = 3 x 1 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 844 and 255 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(18,7) = HCF(79,18) = HCF(255,79) = HCF(844,255) .

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

Step 1: Since 970 > 1, we apply the division lemma to 970 and 1, to get

970 = 1 x 970 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 970 is 1

Notice that 1 = HCF(970,1) .
