HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 621, 847 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 621, 847 is 1 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 621, 847 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 621, 847 is 1.
HCF(621, 847) = 1
HCF of 621, 847 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 621, 847 is 1.
Highest Common Factor of 621,847 is 1
Step 1: Since 847 > 621, we apply the division lemma to 847 and 621, to get
847 = 621 x 1 + 226
Step 2: Since the reminder 621 ≠ 0, we apply division lemma to 226 and 621, to get
621 = 226 x 2 + 169
Step 3: We consider the new divisor 226 and the new remainder 169, and apply the division lemma to get
226 = 169 x 1 + 57
We consider the new divisor 169 and the new remainder 57,and apply the division lemma to get
169 = 57 x 2 + 55
We consider the new divisor 57 and the new remainder 55,and apply the division lemma to get
57 = 55 x 1 + 2
We consider the new divisor 55 and the new remainder 2,and apply the division lemma to get
55 = 2 x 27 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 621 and 847 is 1
Notice that 1 = HCF(2,1) = HCF(55,2) = HCF(57,55) = HCF(169,57) = HCF(226,169) = HCF(621,226) = HCF(847,621) .
