HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 565, 857 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 565, 857 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 565, 857 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 565, 857 is 1.

HCF(565, 857) = 1

Highest common factor (HCF) of 565, 857 is 1.

Highest Common Factor of 565,857 using Euclid's algorithm

Highest Common Factor of 565,857 is 1

Step 1: Since 857 > 565, we apply the division lemma to 857 and 565, to get

857 = 565 x 1 + 292

Step 2: Since the reminder 565 ≠ 0, we apply division lemma to 292 and 565, to get

565 = 292 x 1 + 273

Step 3: We consider the new divisor 292 and the new remainder 273, and apply the division lemma to get

292 = 273 x 1 + 19

We consider the new divisor 273 and the new remainder 19,and apply the division lemma to get

273 = 19 x 14 + 7

We consider the new divisor 19 and the new remainder 7,and apply the division lemma to get

19 = 7 x 2 + 5

We consider the new divisor 7 and the new remainder 5,and apply the division lemma to get

7 = 5 x 1 + 2

We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get

5 = 2 x 2 + 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 565 and 857 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(19,7) = HCF(273,19) = HCF(292,273) = HCF(565,292) = HCF(857,565) .
