HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 520, 775, 711 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 520, 775, 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 520, 775, 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 520, 775, 711 is 1.

HCF(520, 775, 711) = 1

HCF of 520, 775, 711 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 520, 775, 711 is 1.

Highest Common Factor of 520,775,711 using Euclid's algorithm

Highest Common Factor of 520,775,711 is 1

Step 1: Since 775 > 520, we apply the division lemma to 775 and 520, to get

775 = 520 x 1 + 255

Step 2: Since the reminder 520 ≠ 0, we apply division lemma to 255 and 520, to get

520 = 255 x 2 + 10

Step 3: We consider the new divisor 255 and the new remainder 10, and apply the division lemma to get

255 = 10 x 25 + 5

We consider the new divisor 10 and the new remainder 5, and apply the division lemma to get

10 = 5 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 520 and 775 is 5

Notice that 5 = HCF(10,5) = HCF(255,10) = HCF(520,255) = HCF(775,520) .

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

Step 1: Since 711 > 5, we apply the division lemma to 711 and 5, to get

711 = 5 x 142 + 1

Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 1 and 5, 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 5 and 711 is 1

Notice that 1 = HCF(5,1) = HCF(711,5) .
