HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 816, 575 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 816, 575 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 816, 575 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 816, 575 is 1.

HCF(816, 575) = 1

Highest common factor (HCF) of 816, 575 is 1.

Highest Common Factor of 816,575 using Euclid's algorithm

Highest Common Factor of 816,575 is 1

Step 1: Since 816 > 575, we apply the division lemma to 816 and 575, to get

816 = 575 x 1 + 241

Step 2: Since the reminder 575 ≠ 0, we apply division lemma to 241 and 575, to get

575 = 241 x 2 + 93

Step 3: We consider the new divisor 241 and the new remainder 93, and apply the division lemma to get

241 = 93 x 2 + 55

We consider the new divisor 93 and the new remainder 55,and apply the division lemma to get

93 = 55 x 1 + 38

We consider the new divisor 55 and the new remainder 38,and apply the division lemma to get

55 = 38 x 1 + 17

We consider the new divisor 38 and the new remainder 17,and apply the division lemma to get

38 = 17 x 2 + 4

We consider the new divisor 17 and the new remainder 4,and apply the division lemma to get

17 = 4 x 4 + 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 816 and 575 is 1

Notice that 1 = HCF(4,1) = HCF(17,4) = HCF(38,17) = HCF(55,38) = HCF(93,55) = HCF(241,93) = HCF(575,241) = HCF(816,575) .
