HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 851, 544 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 851, 544 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 851, 544 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 851, 544 is 1.

HCF(851, 544) = 1

## HCF of 851, 544 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 851, 544 is 1. ### Highest Common Factor of 851,544 is 1

Step 1: Since 851 > 544, we apply the division lemma to 851 and 544, to get

851 = 544 x 1 + 307

Step 2: Since the reminder 544 ≠ 0, we apply division lemma to 307 and 544, to get

544 = 307 x 1 + 237

Step 3: We consider the new divisor 307 and the new remainder 237, and apply the division lemma to get

307 = 237 x 1 + 70

We consider the new divisor 237 and the new remainder 70,and apply the division lemma to get

237 = 70 x 3 + 27

We consider the new divisor 70 and the new remainder 27,and apply the division lemma to get

70 = 27 x 2 + 16

We consider the new divisor 27 and the new remainder 16,and apply the division lemma to get

27 = 16 x 1 + 11

We consider the new divisor 16 and the new remainder 11,and apply the division lemma to get

16 = 11 x 1 + 5

We consider the new divisor 11 and the new remainder 5,and apply the division lemma to get

11 = 5 x 2 + 1

We consider the new divisor 5 and the new remainder 1,and apply the division lemma 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 851 and 544 is 1

Notice that 1 = HCF(5,1) = HCF(11,5) = HCF(16,11) = HCF(27,16) = HCF(70,27) = HCF(237,70) = HCF(307,237) = HCF(544,307) = HCF(851,544) .
