HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 312, 429 i.e. 39 the largest integer that leaves a remainder zero for all numbers.

HCF of 312, 429 is 39 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 312, 429 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 312, 429 is 39.

HCF(312, 429) = 39

HCF of 312, 429 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 312, 429 is 39.

Highest Common Factor of 312,429 using Euclid's algorithm

Highest Common Factor of 312,429 is 39

Step 1: Since 429 > 312, we apply the division lemma to 429 and 312, to get

429 = 312 x 1 + 117

Step 2: Since the reminder 312 ≠ 0, we apply division lemma to 117 and 312, to get

312 = 117 x 2 + 78

Step 3: We consider the new divisor 117 and the new remainder 78, and apply the division lemma to get

117 = 78 x 1 + 39

We consider the new divisor 78 and the new remainder 39, and apply the division lemma to get

78 = 39 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 39, the HCF of 312 and 429 is 39

Notice that 39 = HCF(78,39) = HCF(117,78) = HCF(312,117) = HCF(429,312) .
