HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 705, 359 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 705, 359 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 705, 359 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 705, 359 is 1.

HCF(705, 359) = 1

Highest common factor (HCF) of 705, 359 is 1.

Highest Common Factor of 705,359 using Euclid's algorithm

Highest Common Factor of 705,359 is 1

Step 1: Since 705 > 359, we apply the division lemma to 705 and 359, to get

705 = 359 x 1 + 346

Step 2: Since the reminder 359 ≠ 0, we apply division lemma to 346 and 359, to get

359 = 346 x 1 + 13

Step 3: We consider the new divisor 346 and the new remainder 13, and apply the division lemma to get

346 = 13 x 26 + 8

We consider the new divisor 13 and the new remainder 8,and apply the division lemma to get

13 = 8 x 1 + 5

We consider the new divisor 8 and the new remainder 5,and apply the division lemma to get

8 = 5 x 1 + 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 705 and 359 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(13,8) = HCF(346,13) = HCF(359,346) = HCF(705,359) .
