HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 353, 434 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 353, 434 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 353, 434 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 353, 434 is 1.

HCF(353, 434) = 1

Highest common factor (HCF) of 353, 434 is 1.

Highest Common Factor of 353,434 using Euclid's algorithm

Highest Common Factor of 353,434 is 1

Step 1: Since 434 > 353, we apply the division lemma to 434 and 353, to get

434 = 353 x 1 + 81

Step 2: Since the reminder 353 ≠ 0, we apply division lemma to 81 and 353, to get

353 = 81 x 4 + 29

Step 3: We consider the new divisor 81 and the new remainder 29, and apply the division lemma to get

81 = 29 x 2 + 23

We consider the new divisor 29 and the new remainder 23,and apply the division lemma to get

29 = 23 x 1 + 6

We consider the new divisor 23 and the new remainder 6,and apply the division lemma to get

23 = 6 x 3 + 5

We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get

6 = 5 x 1 + 1

We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get

5 = 1 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 353 and 434 is 1

Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(23,6) = HCF(29,23) = HCF(81,29) = HCF(353,81) = HCF(434,353) .
