HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 520, 921, 441 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 520, 921, 441 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, 921, 441 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, 921, 441 is 1.

HCF(520, 921, 441) = 1

Highest common factor (HCF) of 520, 921, 441 is 1.

Highest Common Factor of 520,921,441 using Euclid's algorithm

Highest Common Factor of 520,921,441 is 1

Step 1: Since 921 > 520, we apply the division lemma to 921 and 520, to get

921 = 520 x 1 + 401

Step 2: Since the reminder 520 ≠ 0, we apply division lemma to 401 and 520, to get

520 = 401 x 1 + 119

Step 3: We consider the new divisor 401 and the new remainder 119, and apply the division lemma to get

401 = 119 x 3 + 44

We consider the new divisor 119 and the new remainder 44,and apply the division lemma to get

119 = 44 x 2 + 31

We consider the new divisor 44 and the new remainder 31,and apply the division lemma to get

44 = 31 x 1 + 13

We consider the new divisor 31 and the new remainder 13,and apply the division lemma to get

31 = 13 x 2 + 5

We consider the new divisor 13 and the new remainder 5,and apply the division lemma to get

13 = 5 x 2 + 3

We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get

5 = 3 x 1 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 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 520 and 921 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(13,5) = HCF(31,13) = HCF(44,31) = HCF(119,44) = HCF(401,119) = HCF(520,401) = HCF(921,520) .

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

Step 1: Since 441 > 1, we apply the division lemma to 441 and 1, to get

441 = 1 x 441 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 441 is 1

Notice that 1 = HCF(441,1) .
