HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 529, 420, 711 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 529, 420, 711 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 529, 420, 711 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 529, 420, 711 is 1.

HCF(529, 420, 711) = 1

Highest common factor (HCF) of 529, 420, 711 is 1.

Highest Common Factor of 529,420,711 using Euclid's algorithm

Highest Common Factor of 529,420,711 is 1

Step 1: Since 529 > 420, we apply the division lemma to 529 and 420, to get

529 = 420 x 1 + 109

Step 2: Since the reminder 420 ≠ 0, we apply division lemma to 109 and 420, to get

420 = 109 x 3 + 93

Step 3: We consider the new divisor 109 and the new remainder 93, and apply the division lemma to get

109 = 93 x 1 + 16

We consider the new divisor 93 and the new remainder 16,and apply the division lemma to get

93 = 16 x 5 + 13

We consider the new divisor 16 and the new remainder 13,and apply the division lemma to get

16 = 13 x 1 + 3

We consider the new divisor 13 and the new remainder 3,and apply the division lemma to get

13 = 3 x 4 + 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 529 and 420 is 1

Notice that 1 = HCF(3,1) = HCF(13,3) = HCF(16,13) = HCF(93,16) = HCF(109,93) = HCF(420,109) = HCF(529,420) .

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

Step 1: Since 711 > 1, we apply the division lemma to 711 and 1, to get

711 = 1 x 711 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 711 is 1

Notice that 1 = HCF(711,1) .
