HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 891, 84429 i.e. 27 the largest integer that leaves a remainder zero for all numbers.
HCF of 891, 84429 is 27 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 891, 84429 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 891, 84429 is 27.
HCF(891, 84429) = 27
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 891, 84429 is 27.
Step 1: Since 84429 > 891, we apply the division lemma to 84429 and 891, to get
84429 = 891 x 94 + 675
Step 2: Since the reminder 891 ≠ 0, we apply division lemma to 675 and 891, to get
891 = 675 x 1 + 216
Step 3: We consider the new divisor 675 and the new remainder 216, and apply the division lemma to get
675 = 216 x 3 + 27
We consider the new divisor 216 and the new remainder 27, and apply the division lemma to get
216 = 27 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 27, the HCF of 891 and 84429 is 27
Notice that 27 = HCF(216,27) = HCF(675,216) = HCF(891,675) = HCF(84429,891) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
