HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 218, 257, 529 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 218, 257, 529 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 218, 257, 529 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 218, 257, 529 is 1.

HCF(218, 257, 529) = 1

Highest common factor (HCF) of 218, 257, 529 is 1.

Highest Common Factor of 218,257,529 using Euclid's algorithm

Highest Common Factor of 218,257,529 is 1

Step 1: Since 257 > 218, we apply the division lemma to 257 and 218, to get

257 = 218 x 1 + 39

Step 2: Since the reminder 218 ≠ 0, we apply division lemma to 39 and 218, to get

218 = 39 x 5 + 23

Step 3: We consider the new divisor 39 and the new remainder 23, and apply the division lemma to get

39 = 23 x 1 + 16

We consider the new divisor 23 and the new remainder 16,and apply the division lemma to get

23 = 16 x 1 + 7

We consider the new divisor 16 and the new remainder 7,and apply the division lemma to get

16 = 7 x 2 + 2

We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get

7 = 2 x 3 + 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 218 and 257 is 1

Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(16,7) = HCF(23,16) = HCF(39,23) = HCF(218,39) = HCF(257,218) .

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

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

529 = 1 x 529 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 529 is 1

Notice that 1 = HCF(529,1) .
