HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 295, 643 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 295, 643 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 295, 643 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 295, 643 is 1.
HCF(295, 643) = 1
HCF of 295, 643 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 295, 643 is 1.
Highest Common Factor of 295,643 is 1
Step 1: Since 643 > 295, we apply the division lemma to 643 and 295, to get
643 = 295 x 2 + 53
Step 2: Since the reminder 295 ≠ 0, we apply division lemma to 53 and 295, to get
295 = 53 x 5 + 30
Step 3: We consider the new divisor 53 and the new remainder 30, and apply the division lemma to get
53 = 30 x 1 + 23
We consider the new divisor 30 and the new remainder 23,and apply the division lemma to get
30 = 23 x 1 + 7
We consider the new divisor 23 and the new remainder 7,and apply the division lemma to get
23 = 7 x 3 + 2
We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get
7 = 2 x 3 + 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 295 and 643 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(23,7) = HCF(30,23) = HCF(53,30) = HCF(295,53) = HCF(643,295) .
