HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 819, 521, 526 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 819, 521, 526 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 819, 521, 526 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 819, 521, 526 is 1.

HCF(819, 521, 526) = 1

Highest common factor (HCF) of 819, 521, 526 is 1.

Highest Common Factor of 819,521,526 using Euclid's algorithm

Highest Common Factor of 819,521,526 is 1

Step 1: Since 819 > 521, we apply the division lemma to 819 and 521, to get

819 = 521 x 1 + 298

Step 2: Since the reminder 521 ≠ 0, we apply division lemma to 298 and 521, to get

521 = 298 x 1 + 223

Step 3: We consider the new divisor 298 and the new remainder 223, and apply the division lemma to get

298 = 223 x 1 + 75

We consider the new divisor 223 and the new remainder 75,and apply the division lemma to get

223 = 75 x 2 + 73

We consider the new divisor 75 and the new remainder 73,and apply the division lemma to get

75 = 73 x 1 + 2

We consider the new divisor 73 and the new remainder 2,and apply the division lemma to get

73 = 2 x 36 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 819 and 521 is 1

Notice that 1 = HCF(2,1) = HCF(73,2) = HCF(75,73) = HCF(223,75) = HCF(298,223) = HCF(521,298) = HCF(819,521) .

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

Step 1: Since 526 > 1, we apply the division lemma to 526 and 1, to get

526 = 1 x 526 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 526 is 1

Notice that 1 = HCF(526,1) .
