HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 641, 859, 533 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 641, 859, 533 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 641, 859, 533 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 641, 859, 533 is 1.

HCF(641, 859, 533) = 1

Highest common factor (HCF) of 641, 859, 533 is 1.

Highest Common Factor of 641,859,533 using Euclid's algorithm

Highest Common Factor of 641,859,533 is 1

Step 1: Since 859 > 641, we apply the division lemma to 859 and 641, to get

859 = 641 x 1 + 218

Step 2: Since the reminder 641 ≠ 0, we apply division lemma to 218 and 641, to get

641 = 218 x 2 + 205

Step 3: We consider the new divisor 218 and the new remainder 205, and apply the division lemma to get

218 = 205 x 1 + 13

We consider the new divisor 205 and the new remainder 13,and apply the division lemma to get

205 = 13 x 15 + 10

We consider the new divisor 13 and the new remainder 10,and apply the division lemma to get

13 = 10 x 1 + 3

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

10 = 3 x 3 + 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 641 and 859 is 1

Notice that 1 = HCF(3,1) = HCF(10,3) = HCF(13,10) = HCF(205,13) = HCF(218,205) = HCF(641,218) = HCF(859,641) .

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

Step 1: Since 533 > 1, we apply the division lemma to 533 and 1, to get

533 = 1 x 533 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 533 is 1

Notice that 1 = HCF(533,1) .
