HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 693, 434 i.e. 7 the largest integer that leaves a remainder zero for all numbers.

HCF of 693, 434 is 7 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 693, 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 693, 434 is 7.

HCF(693, 434) = 7

HCF of 693, 434 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 693, 434 is 7.

Highest Common Factor of 693,434 using Euclid's algorithm

Highest Common Factor of 693,434 is 7

Step 1: Since 693 > 434, we apply the division lemma to 693 and 434, to get

693 = 434 x 1 + 259

Step 2: Since the reminder 434 ≠ 0, we apply division lemma to 259 and 434, to get

434 = 259 x 1 + 175

Step 3: We consider the new divisor 259 and the new remainder 175, and apply the division lemma to get

259 = 175 x 1 + 84

We consider the new divisor 175 and the new remainder 84,and apply the division lemma to get

175 = 84 x 2 + 7

We consider the new divisor 84 and the new remainder 7,and apply the division lemma to get

84 = 7 x 12 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 693 and 434 is 7

Notice that 7 = HCF(84,7) = HCF(175,84) = HCF(259,175) = HCF(434,259) = HCF(693,434) .
