HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 429, 7644 i.e. 39 the largest integer that leaves a remainder zero for all numbers.
HCF of 429, 7644 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 429, 7644 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 429, 7644 is 39.
HCF(429, 7644) = 39
HCF of 429, 7644 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 429, 7644 is 39.
Highest Common Factor of 429,7644 is 39
Step 1: Since 7644 > 429, we apply the division lemma to 7644 and 429, to get
7644 = 429 x 17 + 351
Step 2: Since the reminder 429 ≠ 0, we apply division lemma to 351 and 429, to get
429 = 351 x 1 + 78
Step 3: We consider the new divisor 351 and the new remainder 78, and apply the division lemma to get
351 = 78 x 4 + 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 429 and 7644 is 39
Notice that 39 = HCF(78,39) = HCF(351,78) = HCF(429,351) = HCF(7644,429) .
