HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 847, 406 i.e. 7 the largest integer that leaves a remainder zero for all numbers.
HCF of 847, 406 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 847, 406 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 847, 406 is 7.
HCF(847, 406) = 7
HCF of 847, 406 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 847, 406 is 7.
Highest Common Factor of 847,406 is 7
Step 1: Since 847 > 406, we apply the division lemma to 847 and 406, to get
847 = 406 x 2 + 35
Step 2: Since the reminder 406 ≠ 0, we apply division lemma to 35 and 406, to get
406 = 35 x 11 + 21
Step 3: We consider the new divisor 35 and the new remainder 21, and apply the division lemma to get
35 = 21 x 1 + 14
We consider the new divisor 21 and the new remainder 14,and apply the division lemma to get
21 = 14 x 1 + 7
We consider the new divisor 14 and the new remainder 7,and apply the division lemma to get
14 = 7 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 847 and 406 is 7
Notice that 7 = HCF(14,7) = HCF(21,14) = HCF(35,21) = HCF(406,35) = HCF(847,406) .
