HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 432, 521 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 432, 521 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 432, 521 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 432, 521 is 1.

HCF(432, 521) = 1

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 432, 521 is 1.

Highest Common Factor of 432,521 using Euclid's algorithm

Highest Common Factor of 432,521 is 1

Step 1: Since 521 > 432, we apply the division lemma to 521 and 432, to get

521 = 432 x 1 + 89

Step 2: Since the reminder 432 ≠ 0, we apply division lemma to 89 and 432, to get

432 = 89 x 4 + 76

Step 3: We consider the new divisor 89 and the new remainder 76, and apply the division lemma to get

89 = 76 x 1 + 13

We consider the new divisor 76 and the new remainder 13,and apply the division lemma to get

76 = 13 x 5 + 11

We consider the new divisor 13 and the new remainder 11,and apply the division lemma to get

13 = 11 x 1 + 2

We consider the new divisor 11 and the new remainder 2,and apply the division lemma to get

11 = 2 x 5 + 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 432 and 521 is 1

Notice that 1 = HCF(2,1) = HCF(11,2) = HCF(13,11) = HCF(76,13) = HCF(89,76) = HCF(432,89) = HCF(521,432) .
