HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 426, 669 i.e. 3 the largest integer that leaves a remainder zero for all numbers.

HCF of 426, 669 is 3 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 426, 669 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 426, 669 is 3.

HCF(426, 669) = 3

HCF of 426, 669 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 426, 669 is 3.

Highest Common Factor of 426,669 using Euclid's algorithm

Highest Common Factor of 426,669 is 3

Step 1: Since 669 > 426, we apply the division lemma to 669 and 426, to get

669 = 426 x 1 + 243

Step 2: Since the reminder 426 ≠ 0, we apply division lemma to 243 and 426, to get

426 = 243 x 1 + 183

Step 3: We consider the new divisor 243 and the new remainder 183, and apply the division lemma to get

243 = 183 x 1 + 60

We consider the new divisor 183 and the new remainder 60,and apply the division lemma to get

183 = 60 x 3 + 3

We consider the new divisor 60 and the new remainder 3,and apply the division lemma to get

60 = 3 x 20 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 426 and 669 is 3

Notice that 3 = HCF(60,3) = HCF(183,60) = HCF(243,183) = HCF(426,243) = HCF(669,426) .
